No, just the stuff I have listed in my sig.

dude, you REALLY should go back to stage 1. your REALLY risking blowing your engine. the stock internals CANNOT keep up with a stage 2 map.

I'm mechanically stock for now...

Even with our higher altitude the stock pump can't keep up with stage 2?

of late, i have been seeing it more often of people running a stage 1 map while stock.

Just make sure you keep an eye on your AFR's.

Oh, and get an intake.

lol

Hmm... I'll have to take it into consideration. I've been running Stage 2 for awhile now and things seem fine so far. No crazy temps, good A/F mixtures, spec LTFTs, and (what I think) are good fuel delivery numbers. (?)

I guess to quote the great Ivan Drago- If he dies.... He dies.

the biggest thing is that your fuel pressures should not drop below IIRC 1600 under hard acceleration.

also, watch your KR.

Sounds good, I'll get back into the habit of data logging more often, now that it's getting hotter. My KR numbers were really great last Summer, after the addition of the TMIC, and from what I recall, I was always pushing high 1600's for fuel pressure, during WOT. If those numbers start coming down, I'll look into getting an aftermarket pump; I know that TheRPMStore sells 'em.

this is a recommendation to ALL speed owners.

I recommend Autotech FP internals. You can get them for $350 from most places, and are quite simple to install with the same results.

save ya some cash-ola!

1650 is the preferred number 1600 absolute lowest....

COspeed6 · Postby **COspeed6** » Thu Apr 05, 2012 9:14

So the consensus is that if your HPFP can hold more then 1650psi you can turn stage 2 with a only test pipe and it will be fine, minus the possible negative effects on the primary cat in the stock dp? Correct?

All i can tell you, is what Cobb recommends for the stage 2.

I personally wouldn't run a stage 2 map without a downpipe. Per Cobb, that means you don't have the necessary hardware for running stage 2. Intake = Stage 1, Downpipe = Stage 2. And there are modifications for intercoolers, etc. They wouldn't go to so much trouble making so many different maps for every hardware combination if it wasn't important.

I'm guessing maybe altitude is letting some get away with running a stage 2 map without the necessary hardware, I don't know. But along the lines Mortose was talking about, I would also keep an eye on EGTs. If they are getting crazy high, bad things can happen. You don't want them much higher than 1500-1600deg at WOT. If you start getting up around 1800, then you might want to consider going back to a stage 1 map, even if all the other stuff you are monitoring looks fine.
