I have an 06TBSS in my 58 Sedan Delivery. I have a mild cam and long tube headers. I went to a ls3 "card" style MAF and it's never ran that great. I recently decided to go back to the stock MAF and while trying to restore the stock tune I apparently ruined the ECM according to HPT support. So, I have an 05gto for another swap that I pulled the ECM from and the car starts now but has no throttle response. The suite shows the TPS % changing but I don't think that the throttle plate is moving. If I pull the plug on the throttle body the car stalls. I replaced the throttle body and MAF with the gto set up and nothing is changing. If I pull the MAF or MAP plug nothing happens. I've never had the gto running but I'm assuming it did when it hit something hard!
Please help!
