Smashed Down 1060rwhp on pump gas ! Hey guys, I don't post on LS1Tech very often, but I figure you would all love to share in my experience. I had my local boys build up a beautiful Forged 402ci 9.2:1 Motor with ETP 226 heads. I designed and fabricated a "Back Yard Custom" Twin GT35R turbo kit for my Corvette C5 Coupe. We cracked 800rwhp @ 10psi late last week and broke the torque tube on the dyno 
I had a local shop build me a molly tube and got it back in the car this morning. I have been working on getting my boost controller setup, and we made a few pulls for my pump gas tune. She only made 12psi upto 5000rpm and then creep'd upto 16.5 psi by 6500rpm. It looks like I will need to ramp up the gain on my boost controller to get my mid range power up to par. She is already smoking the tires on the dyno

Congrats on the results, looks like nice fabrication!
that kind of power on low oct is just a time bomb. Ive made XXXX on the dyno also on 93 but would never risk pushing it on the street or track at that level, only good gas there.

Thanks for the props guys 
The 1600rw/tq was just a spike on the dyno. We lost the rpm signal a couple of times to.
Here are a couple of dyno graphs of the speed vs rpm plot.
