I got the new actuator and the connector for the valve today, so I installed everything. First I was trying to reuse the body of the old actuator, but it wouldn't work since the bottom is a bit different. The new actuator has the bottom port rotated about 15 degrees off where it was, and it's a different thread pitch, so I went to Whisler Bearing to get a couple new fittings (3/8NPT to 3AN nipple). Luckily they had what I needed. So I was set! Or so I thought. I realized once I got everything back together and Whisler Bearing was closed, that one of the braided lines I'm using is now too short, the one that goes to the port that's been rotated, for seemingly no damn reason. Ugh.

I got the new bushing for the old actuator today too, so I installed that, and there is still air leaking out the back of the actuator. So I guess it doesn't really matter? I installed the old actuator and ran the car tonight, and I'm still only getting about 14psi now, which I guess is a little better since I was only getting 12psi before, but I was supposed to be getting either 16 or 18psi, I don't remember which I had selected.

I cut some more metal out of the heat shield in an attempt to make it work, but it still wasn't enough and I gave up. So I just wrapped the wastegate in some heat shielding and left it at that. And I swapped out the 14psi spring that was in it and put in the 5 and 7psi springs to make 12psi.

This is the inline ball joint I had picked up to modify the old actuator, next to the new actuator and it's ball joint. Very similar.

Monday after work I went to Whisler Bearing and got a new line made and installed the new actuator, but I didn't test it until tonight. Still not fixed. So now I'm guessing it's either the ECU or maybe the baro pressure sensor or something, because I've already replaced the actuator and 4 port valve with no luck.

I was looking online the other night, making sure I had the lines plumbed right. I found a pic that had the two lines coming out of the solenoid swapped, so instead of the top line going to the top of the actuator, going to the bottom instead. I swapped them and tested it. I definitely got full boost, and then some. And once I hit about 20psi the car started bucking. I'm not sure if that was due to the fuel map being too lean or the actuator slamming open and shut. I guess it had to be the fuel map since the wastegate opening and closing wouldn't have made such a huge difference in acceleration.

Chris told me to put the 3 port solenoid back in. I installed the BCSV that comes with the EFR turbos and tested it tonight. Still no luck. The springs in the new actuator should be opening the gate at 12psi but I'm getting about 15psi no matter which boost setting I choose.

On top of all that, I'm in bad need of tires, and I really don't want to buy new ones right now, for a couple reasons.
1. I want to fix the damage to the right rear wheel before I get new tires, and I REALLY don't have the money for that.
2. I wanted to have some spare wheels and tires for the winter before I get new track tires, that way I can bring the track tires inside for the winter so they won't get ruined.

Last Friday night I installed new firmware and software on the ECU, and pretty much bricked it haha. Chris logged in Sunday afternoon and fixed it easily though. I took it for a drive again and boost was still messed up. I sent him some logs he said he'd look at. I'm also going to try changing the vacuum hose routing again.

I ordered some tires a couple days ago, should be here tomorrow. Kumho Ecsta V720, all four for about $615 shipped. Not bad at all, that's about half what I usually pay for new tires in this size. Andy has two sets of them and he likes them. They handle well on the track and apparently don't wear bad either. I was looking at a full set of used Hoosier R7s but I wasn't sure how they'd handle on the street and read that I'd probably only get about 1500 miles out of them. They were only $400, but financially it still didn't make sense.

I started looking into TPMS again too. Mine is still working, aside from a couple batteries being dead so the readings no longer show. I might end up just replacing the batteries for now and going with it. The one I have is no longer available, also. But I did find some cool options while looking. I started seeing ones that just use a receiver and plugs into a stereo that has Android Auto and shows the readings on the screen through the app. And the cool thing is that the app doesn't have to be open to see alerts about a tire losing air or whatever, it will pop up on the screen over other things. The only downside is that I can't plug my phone in to use Android Auto at the same time, but I don't ever do that anyway. I didn't even have it set up until last night. I'm also going to use internal sensors again. I found a few options on Amazon but ended up buying it from Phoenix Automotive. Although it looks pretty much exactly like some others I've seen on Amazon lol.

I got the new tires on Friday and decided to just replace the batteries in my current TPMS sensors instead of waiting for the new kit to get here, since they hadn't shipped it yet (and still haven't, even though I ordered it Thursday). If they don't ship it by tomorrow I'll probably just cancel the order. Big O pulled the tires off and I saw the batteries are CR2050. Easy enough, I'll just go to Batteries+. Well, they didn't have any, said I'd need to order them online because there's some $10k insurance they have to have in order to ship the batteries. I tried King Soopers and Ace Hardware too, neither had the batteries. However, a CR2025 is the same diameter but shorter. I bought a few of those and put one in and it worked. However, I started thinking under centrifugal force, the batteries might lose contact inside and cause problems, since they're shorter. I put a couple pennies in and it looked like it would work OK but I got nervous about that. Brett suggested using a spring, and I almost did that, but I found the batteries online somewhere (not even Amazon has them). So I ordered four of the batteries, and if the batteries get here first I'll just put those in, but if the new kit gets here first I'll try to install that instead.

Chris got back to me Friday and said the TPS wasn't getting all the way to 70%, so I looked into that Saturday. Turns out I just wasn't pressing the pedal down all the way. He had me verify the TB plates were opening all the way too and they were. He also made some adjustments to the logging software so we can get more info next time.

I'm so livid right now.

The TPMS kit I bought from Phoenix Automotive was about $20 more than what I would have paid on Amazon, and I paid extra to have it shipped through FedEx, hoping it would get here earlier. I bought it last Thursday. I checked Friday morning, not shipped yet. I checked Monday and it had a shipping label created but hadn't been dropped off yet. I emailed them today and told them if it hadn't been shipped yet that I wanted a refund. So they shipped it today and said it's already in transit. No bitch, you JUST shipped it today and only after I had to ask about it. How many damn days would I have been waiting if I hadn't emailed?!

I found the batteries at Batterymart.com and bought them Saturday. I checked tracking with them as well, nothing until today...after I had emailed them asking about the status. They also didn't ship the batteries until after I had already emailed. WTF is with these companies?! So now this weekend is shot because I won't get any of this stuff until next week, and I was trying to do a fun drive this weekend. Ugh.

I got the batteries on Saturday so I put them in that afternoon around 315 and I messed up one of the contacts while trying to get the battery in. The solder broke, so I had to resolder it. Then while I was removing the sensor from the wheel I lost one of the washers so that took me a bit to find also. It took me a bit to find a place to mount and balance them but I finally found a place. I drove on them for the first time today and I must say I'm very pleased with these tires so far. I had read reviews and people said they were really loud, but I didn't hear anything at all. Maybe it's because my car is too loud and it's masking it, but I feel like these are more quiet than my AD08s. I haven't had a chance to test their grip yet but supposedly they're really good, so Andy says. And they were about half the price of other tires in this size.

I haven't received the new TPMS kit yet, but I'll probably install the receiver and see if it'll work with my current sensors, since they're on the same frequency. We'll see. But if not, no biggie, I can wait until next time.

I didn't realize I hadn't updated this for a bit.

I raced on the new tires last Sunday. Holy SHIIIIT. These tires are RIDICULOUSLY sticky. Especially for the cost. I guessed that my fastest time of the day would be a low 50s. My very first lap was 48.6, then 48.1, then 47.5. But that was the fastest I ran. And honestly I wasn't pushing it as hard as I could have. I'm not sure I reached the full potential of the tires, Andy says I wasn't pushing them to the limit. IDK, we'll see. I just know they're my new favorite. The fastest times of the day were in the 43 second range, and that was from a VERY built Lotus, and a very built MR2, and a Porsche GT3 driven by a very good driver. So I feel pretty good about this. I didn't even drive that great either.

And I think my suspension setup is finally pretty much perfect. I never had any issues with oversteer or understeer, and I set the front struts damping quite a bit higher just so the body wouldn't roll quite as much.

As for the new TPMS kit, what a joke. I tried installing the app on my stereo and it wouldn't work. On top of that, the batteries definitely were not replaceable in the sensors, unless you melt the sealant on the back and do it that way, which I'm not even 100% sure would work, just going based off some youtube videos. And all that after the shipping issues I dealt with in the beginning. I contacted the company and they said the app only works on their stereos. Oh ok, so when I asked if I needed anything other than this kit, and if the batteries were replaceable, and you said no and yes respectively, you were lying through your teeth?! From what I understand their stereos are shit too, and they don't even make any that fit a regular din or double din slot, not that I'd want one anyway. So I asked about a refund and they sent me a link to fill out some information. I did that, no response. I emailed them asking about it, again no response. I'm wondering if I can file a Paypal dispute. Might be too late. I gave them a bad review but it never showed up on their site. Go figure. I posted on facebook about it too. Such a crock.

I'm still having boost issues but for the moment I'm not going to worry about it. I really need to find some cheap tires to put on my old wheels so I can put them back on for the winter and bring my nice tires inside.
