What did they rev it out to? When I did mine (15 with stage 2) it was 625whp to 7k rpm. Then I dynoed 685 reving out to 7500

It was dropping off at like 6800. Its started pulling timing at 6500.. Total of 4 degrees by the end of the rev. It got to.. For an 18 gt.. The numbers should be upwards of 720++++ to the wheels.. The 15s dont have as much hp. As far as I know...

4 degrees KR will kill your power. You’re probably losing 100+ rwhp due to that. Try different 93, try boostane, log your KR with the tomahawk and see what the effect is.

what gear was the pull done in?

If i'm not mistaking 18's need to be done in 4th as it's 1:1

Yes exactly . I was told by the dyno guy every deg. Is about 25 horses.. So that would put me right where I should be...

Yes. Correct

You and someone else seem to be having similar detonation issues and excessive retard. Are you sure the intercooler pump is on and water is circulating?
