Is there anyone that can verify or direct me to documents that tell me what a dealership can or can not tune on my 2.2?
Is it possible for them to slow down throttle or adjust air fuel mixture?
I had them change a fuel sensor then my car would die on WOT so they had it all day and they claim did fuel pump (which was fine before they did sensor) now the car feels slower to me I know my car. Took it to another dealer after my dealer said there is nothing to adjust. Another dealer saying that without custom tuning nothing can be adjusted.
I just want my car to run proper on stock settings for now, I think they slowed throttle response or made it run a little leaner.
