I have a Gen 7 system new in the box sitting around. I had purchased it a few years ago for my Limited Street car and sold the car before I ever used it. Is it worth while for me to use on my 2k Formula? It is a header and cam only car right now. Dynoed 403 at Speed Inc but could do better as far as idle and driveability are concerned. Or should I just spend some time tuning the stock PCM for this stuff.
