Yesterday I went to get my car tuned after my engine build & upgrade to the Procharger D1 & we ran into some issues with the MAS pegging out at around 4100 RPM. This was with a MAFia extender. We tested it with another MAFia, same result. Test with another stock MAS, same result. It looks a though there is no enough range in the stock MAS. After doing some searching, I think the HPX MAS may be my answer. It is a 3 hour drive to my tuner so I want to make sure this will solve my issue before I make another trip.
Has anyone run into the same issue & what did you do to correct it? Thanks for any .
