cobb ap

    Bad cobb tune? or other problem.

    I'm running a cobb stage 2+aem (lwg) in my gr (invidia cattless turbo back and an aem intake) My fuel injectors and fuel pump are running 100% duty cycle. My Afr is rich and target boost is 18 it spikes to 21 sometimes). If I do a 3rd-4th pull engine will cutout going into 4th.
