I installed a pro m efi system on a 95 mustang gt. I had all the info installed at Pro M. Here is my problem and i want to know if others have this issue, since i cant find anyone with this issue. my car does not idle and it surges, it also is really inconsistent on power. so i took it to a shop so it can be tuned. i have no vaccum leaks or exhaust leaks. The tuner calls me and tells me my car is innconsistent one pull it will make over 400hp and the next will be under 400hp. I just want to know if anyone has problems with this kit or if they know someone who has problems and if they were solved.
really need help thanks Scott.
