i was afraid a box tune wouldent cut it. long story short i had to replace a faulty PCM and went with one from ZZP as a replacement and i am thoroughly impressed! how would i find somebody near me that could tune for me? i thought about E85 instead of all the bolt ons because of the relative simplicity of it. that and E85 is a healthy dollar cheaper than regular gas. i see alot of turbo guys running E85 to combat detonation and i assume that theres a pretty good relationship between detonation and KR. still a little fuzzy on what KR is but i'm getting there, my understanding is that KR is the computer sensing knock and adjusting timing to combat it. number 1 the car has to be reliable above all else, second is power followed by running cost. i try to build everything i have so that i can always afford to drive it, i also have a 79 vette project that belonged to my dad and a old pickup that was my grandpa's new. i like diversity!
