Thats why I had that note in the beginning of the video. The dyno was displaying SAE correction factor. Like all other aftermarket companies, we advertise STP correction factor. The final STP number when we were done was 640.

LS7 + $8,400 = over $20,000 for 640hp? Not trying to bash because I know you guys make some of the best stuff around, but I just wanted to know why so expensive?

I think that was awesome espcecially watching the change in A/F as the RPMS climbed little by little. Must be one killer motor once inside a Z06.
