Tuner turned off certain DTCS, have questions
So my tuner did a very... 'meh' job tuning my H/C/I camaro, and I'm in the process of redoing/fixing it. I was going through what DTC's are turned on/off and I noticed that he had P0106 (MAP Sensor Range/Performance) and P1133 and P1153 (Bank 1/2 Sensor 1 Insufficient Switching) set to No Error Reported. Is this a pretty standard practice when dealing with a modded N/A motor? Or does this sound like my tuner was trying to cover up shoddy work?
Thanks!
