Finally Dyno'd and Tuned APS TT!
Well I finally got around to getting my Z dyno'd and tuned...big suprises occured!
First of all, huge thanks to Altered Atmosphere for the great job on the tune...specifically the owner, Mike. http://www.alteredatmosphere.com
So anyways, I went expecting at least 350-370 off the bat. Turns out I was running SUPER rich...in fact, below the charts rich...under 10. Dyno number...322whp.
Mike then starting tuning the unichip, and fixing the A/F curve....After about 1-2 hours of tuning, the new whp rating in 94.5 degree weather....392.54 at a little less than 9lbs of boost WITH stock cats!!! Keep in mind also that the boost was only adjusted for about a 1/4 lb...that's it. Suffice to say, I am very happy! Here's the dyno chart:

Congrats! I got 442whp on a dynapack with APS test pipes, Nismo exhaust and plenum at 9lbs from Tuan/GRD in 80 degree weather, it's good to see you did 392whp on a dynojet with stock cats.

I wouldn't worry about 12.1 unless it was near redline. Even though the motor's torque peak is around there, it's making much less heat than a higher rpm would.
I see, I never thought of that....
