Well after going through the whole car, everything checks out. Car runs strong, idles perfect. No more knock. Now my only problem is that the tuner is saying he can’t push any further bc of the low quality fuel. As of right now the custom tune is as fast or slower than the OTS 93 map. Is anyone else running a custom 93 tune in the Midwest with this issue?
