U7191 throwing a P0171 lean code on Vette
U7191 throwing a P0171 lean code on Vette
Here is what I got. '05 Vette. Air Raid CAI. FAST 102 intake, LG long tube headers, 2 1/2 inch X pipe with SLP loudmouth 2 exhaust. I just put the headers on and all was fine until that. Running the 91 octane tune and now throwing a P0171 (Bank 1 too lean) code. Any advise to fix this. Was told by the local Diablo sport dealer to ditch the tuner in favor of HPtuner. Running 91 tuner due to Oklahoma gas is 91. 93 is hard to find.

you need to get a custom tune done for your predator/car, that's all...

Yes. Bad dealer. Even if you got HPtuners. Its a huge learning curve. Your mods would take awhile for you to figure out and get it right. I say you need to talk to 06MonteSS and shoot him some logs. Get a custom tune. Then if you want get HPtuners and start learning and reading. And reading some more. But for now let him help you.06MonteSS wrote:you need to get a custom tune done for your predator/car, that's all...
