Hi Guys , I have a BA XR8 Auto with a very poorly modified file.
There are literally hundreds of parameters changed and the vehicle runs very poorly and has erratic trans shifts.
I am considering writing in a complete replacement file from a stock calibration read from the same year model.
Just not sure how I go about this and how many credits this may consume.
Would I be better to just get another PCM and licence that and then tune from there.
Any thoughts please.
Ashley.
