Well, I finally got my car over to a dyno today to have the A/F checked out. I called Sound Performance in Bloomingdale and they said to just bring the car by and they'd strap her down to the dyno. The car was running a little lean, but nothing TOO bad. I mean, I tipped 12.4 a couple times, and the a/f curve was a bit irratic. Jerry from Sound Performance saw that I was using a Predator and went ahead and made a couple adjustments. All in all he ended up adding 5% fuel to 4k+ rpms, and 2% fuel to the lower rpms. He also retarded the spark by 2% I believe (not positive about which way he went on this one though....). After the final dyno, I'll probably go in and take out 1% fuel out of the lower rpms as the a/f was a tad rich (avg about 11.4 in the lower) Anyhow, at the end of the day I ended up (after about 5-6 pulls...) with 437rwhp/472rwtq. The HP seems a little low, but this was also on a Mustang Dyno, so the actual number might be a little higher. Also, they stopped the pull around 6200rpms I think, so it may have gone a little higher if they went to redline.
Here's a pic of the final dyno curve:
Here's a pic of the first and last dyno curve...ignore the initial torque curve as they didn't calibrate the dyno correctly for the first run...
Anyhow, I got confirmation that the tune wasn't "horrible" by any means, and now I'm certain that the tune is again good to go... I'll also throw a props out to Sound Performance for getting me in and taking a little extra time to clean up my a/f curve a little bit... :biggthump
