Garret Stage 1 turbo and SCT tuner w/code P1120
Hey guys, just finished doing a build on a 2005 F350 w/Garret stage 1 AVNT turbo, black onyx gaskets, studs, MKM 6.0 solution and SCT Livewire preloaded tune. Truck runs mint, but Im gettin an MIL w/ code P1120, maf sensor issue. Problem is, this truck has no MAF sensor from the factory. I called SCT, they think the truck had a tune in it before and wasn't returned to stock before the Livewire tune was installed. My customer just purchased the truck before the head gaskets AND turbo let go and doesn't know the performance history to confirm or deny the possibility. Additionally, SCT simply suggested having a custom tune written and to speak to 1 of their custom dealers. I know its a long shot, but has anyone ever come across something like this?
