Sorry to reopen this thread. But after reading it, it reminded me of how much J&R performance in Elmont SUCKS. It brought back memories of how cheated I felt after I had discovered what they had done. To make a long story short, I had them "tune" my fuel maps on my FD and fix my over rich condition. At the time I was not very familiar with the PFC and how to tune. But after learning how to use the thing, I quickly discovered that the map loaded to the PFC where so lean that I'm surprised that I didn't blow my engine. For those familiar with the pfc, they had put a 0.69 fuel correction in almost all of my boost/high rpm maps.... that's probably something like 25:1 AFR!!!! Don't bring your car to these people unless you want to get cheated
