RHS 225s
Comp .243/.247dur .655/.656lift on a 114lsa
Fast 90/90

Air fuel was like 12.8 if I am not wrong and the bitch made 370rw.

Futral did a mail order and the wot seemed to be pretty good. We took it to the dyno with that tune and some idle tuning and it made 354 and we wound up picking it up to 370. That is as far as we have made it and I'm wondering if there is anywhere else to go.

Besides the low numbers, how does it run? I had a similar problem with my setup and it turned out that it was 1/2 a tooth out on the cam.
