Yeah, my stock IX plugs were shot so thats why I gained a bunch of power at one point.
My setup tends to go through plugs faster than a pump gas stock turbo evo. The COP setup definitely lets me get a little more life out of the plugs and Chris I also noticed leaving stop lights and part throttle cruise areas cleaned up very noticeably for me.
Did I gain more top end power from the COP? Highly Doubtful. Did it clean up some driveability on my specific set of mods and E85? Yes!
I can probably push the car past 35psi without worries of blowing the spark out now too. Of course 50K+ miles of 30+psi on the factory original headgasket and head bolts, I may be asking for trouble over 35psi.
