Good evening, I have been considering several different tuners around the tri-state area and have come across J & M Performance based out of Manchester CT. I was just wondering if anyone has any feedback on their reputation and their knowledge of Mustangs and tuning. Apparently they are an SCT dealer which is a plus since I am considering an Excal 2 along with a gear swap, upper elbow and TB, and X pipe. I would appreciate any comments... good or bad.. Thanks in advance.
