The AP is far superior and the OTS maps are far more aggressive. However, the Hypertech is much safer, unless you get a custom tune on the AP that has a more modest increase in Boost, say 2-3psi... as that's all the Hypertech increases in terms of Boost anyway.

Good price here, http://www.truckaddons.com/hypertech/max_energy-sport.html and here if you're interested, http://sparkplugauto.com/denso/iridium-power/denso-iridium-power-itv22-spark-plug.html .

Personally, I'm very happy with the Cobb AP. Will be getting the plugs soon.

Just a little more info on "colder" plugs. http://www.ngk.com/charglossary.asp?kw=Heat+range
