Hello friendly ephatchers,
I'm currently using the k20a2 greddy turbo kit 550cc calibration and it runs lean at WOT at about 12.5 a/f and 6.5 psi. Please help with a calibration good enough for daily with some decent power gains. The closest place to me that tunes is 4 hours away. I really don't want to change any of the parameters risking a motor. I have listed the mods that I have below.
Anyone want to help a friendly ephatcher with a calibration close to my setup?
