08 turbo sierra codes p0121 and p1101
I keep getting these 2 codes since I put in a 2 bar map to read boost in hp tuners. Changed throttle body out with another and same codes. Running through MAF still and truck runs great. I believe it's an issue with the MAF, MAP, and TPS not being within range of what the virtual VE says it should be. Is there a way to tune this out other than disabling the codes? Thanks.
