Your 2006 GT has 2.93 final drive. That Eclipse has 3.3325 final drive (3.777 if its a 6 speed) Also Grand Prix's suck in the higher RPMs. There is just no power there. You were doomed from the get go.

I didnt expect added hp by 110, i expected zero kr... shift kit was just a quick easy mod, and I didnt expect hp, or faster r/t on that either.. the overkill pcm made a big improvement , especially on stock pulley.. t stat and 605s were just to add with the supporting mods
