REP is a fail safe mode for vehicles with ETC. Does it have traction control with an ETC? That is the only way a 01 Silverado would have ETC. TPS is reading 100% when? Any codes when it goes into REP?
surely you arnet using a stock ECM for a wild engine like that...Originally Posted by 55buickrr
Tuned several of the tall deck 450CI+ World LS Blocks with stock PCMs. Just time consuming vs using a Holley
Time for a wiring schematic and DSO/multi-meter.
