JDM Engineering in Freehold tuned mine. Did 540 on a Mustang dyno at 16# boost; that was with a 3.5 upper on the Whipple. Have run 18,000 miles since as my DD without any problems. My only complaint with their tunes is the idle. Took a bit of fooling with the TB to get it right, and even then it's a little weird every so often.
Correct on the Dyno Jet at JDM. Jim D'Amore was here in Houston and tweaked my install and tune at Dyno Joe. I bought all my stuff from JDM. It was a little high priced, but the guy spent most of a Sunday redoing my vacuum lines and generally checking things out - at least wanted to be sure the stock fuel pump was up to the job.
That's him and me at 10:30 Sunday night putting the finishing touches on it in bro in law's garage. What more could you ask for product support?
Ok thanks guys yeah I heard of that place before. Someone told me that accelerated motorsports in doylestown pa was good. Does anyone no about this place please let me no
