Did 120 miles yesterday and tuned most of the way. It is running very very good at these #'s. Rode 800-1500 feet. Below 1000 i was still hitting rev limiter with 74 grams in. Even a couple times above 1000. Gonna try add some more weight yet i guess. The more i drive this engine the more power it seems to make!! I still think these numbers are a little rich on the top end. Next ride i am going to pull a couple more numbers out from 7500 and up. Right now it's running 11.4-11.7 AFR above 7500. The rev limiter needs to be disabled with this engine below 2500 ft i think. It just revs so fast and high that it trips it a lot unless the engine is very loaded. A couple minor inssues that never really bothered me during the 120 mile ride yesterday. About 300 miles on it now.

Lifting this thread again.
I tried out most of you numbers, but it seems to run a little rich. What a/f ratio do you have with these numbers?
When my exhaust valves open i see a a/f ratio drop from 13.5-14.5 down to 11.5-12.5. It stays at that same ratio all the way from around 5500-6000 to 8400 WOT.
It stutters alittle on low rpms, and i have got some bogging, but nothing consistent, and only 2-3 times.
