AF was averaging right around 12.hi(89-99) above 2400
wish i had numbers below 2400
fuel fattened up the higher RPM.
just looking at it now-I bet my idle circuit is a little too lean.

tq started dropping off after about 4200 but was above 190 from 2750-up


pretty nice..

what this tells me is i have a little timing/spark issue, probably a cam timing issue or not aggressive enough cam and the trans is a real power robber.

I'm getting enough fuel(maybe not being burnt correctly) but i think EFI will help me too.
