It's not uncommon, depending on your setup, to get an occasional popping.

Default The main positive difference I was shooting for with the PC-16 file was.....

to eliminate the 130 mph speed limiter. That worked, it's gone, although I haven't actually tested that yet. :-/

As far as tuning it, it seems to be much more easily tunable for low throttle & WOT, but mid-range seems to be about the same. Haven't had too much time to play with that just yet.

There's a freshly rebuilt 6 speed trans in it now, just finished waxing it this AM, and I'll have it at the dyno day on Saturday. If there's an open spot, I'll throw it on the dyno again. I fully expect the GIAC programming to do better than the ATP, which hit 335 whp.

Asking price is $16000, & I can easily justify twice that amount.
