Need a Tuner Willing To Help Heavily modified 2006 GT. if I step into it, car goes into limp mode usually around 5000 rpm+. Must approach high rpms slowly or car limps. predator tells me p2105 and p2106 throttle actuator error. Changed throttle body back to stock. Same thing happens. My thoughts are engine goes lean at wide open throttle and computer doesn't like it and shuts it down. Choices are retune or get higher capacity injectors and fuel pumps. Called guy from Vortech who tuned my car to begin with but he wasn't happy to hear from me. Won't return my call. I need to deal with someone new in the L.A. area who is knowledgable and capable of solving my problem whether it be a retune or whatever. Current shop is Extreme Auto. but they contract tuning out to Vortech engineer who isn't much help right now. Recommendations please.
