Was this Standard or SAE? Can you post a picture of the dyno print out. I Live in the area and get my tuning done at PSI down in Portland. I Made 318 at 8k rpms with Gen3's, Z1 tests, and Tomie y & y-back on a Dyno jet using standard correction. ON a different dyno I made 297 using SAE with a 5 smoothing factor. My AFR was 11.3. I as well blew a O2 bung off at the weld and had to have it rewelded. I was still making power at 8k, Jason at PSI asked if I wanted to raise the rev limiter even higher since power had not fallen off yet, I had him actually drop it down to 7.7k and made 316. I have seen a few people on here once crossing the 8k threshold the oil pump frags out. Mine never peaked, was a straight line all the way to 8k.
