Hello All,
I just joined and I am purchasing the mpvi2 and I will be learning how to tune my car myself as I have had issues with other people/vendors tuning my cars in the past. I feel that my lack of tuning knowledge has been taken advantage at times. I may be wrong but wanted to ask you all so I can relieve myself of the stress.
My car has longtube headers, high flow cats and a cold air intake. A guy that I know offered to tune the car for me with HP tuners. After the first tune, I still got rear o2 codes. I took my car back and the codes were shut off. I plug up my scanner and ALL of my I/M monitors are set to N/A. Fuel system, o2 heater and monitor, catalyst monitor, evap, misfire monitor. etc.
Do all those monitors need to be turned off? Im also getting a service vehicle soon message on my dash but I have no codes????
ANY help and feedback is greatly appreciated. I don't race it or beat the crap out of it but I would like to make sure the car is OK.
Thanks everyone! Glad to be a member
