Hey guys im new to this tuning thing but I have friends asking me for help anyways. I have a friend that removed a supercharger from his 2005 Silverado 4x4 now it will run for a few minutes then it just dies. I scanned it and got dtc's PCM] P0068 - MAP/MAF - Throttle Position Correlation (SES) (Pending) (Old) (History) (Current) (Immature)
[PCM] P0102 - Mass Air Flow (MAF) Sensor Circuit Low Frequency (Old) (History) (Current) (Immature)
[PCM] P0106 - Manifold Absolute Pressure (MAP) System Performance (Old) (Current) (Immature). From the little bit of knowledge I think its pretty obvious the pcm has to be retuned but I dont know where to start. The truck does have a cam and torque converter upgrade but the owner is not sure if its a 2500 or 3000 stall and cold air intake and anywhere between 100 to 150 shot of nitrous. Any help would be very much appreciated.
