I would run it a little richer then that, around 11.5 to 11.9 , seems like it was too lean, but thats just me. ALso how much timing are you running?

Re: dyno graph of 245rwhp

correct me if im wrong.. but isnt the ideal A/F for my setup 11.8 to 12:25.1? i want to make the most power and at the safest level. running rich is power robbing. lean is where the power is but again, there are “safe tune” issues to address to keep the evil detonation monster away. too lean and you burn a piston, knock the ring lands off them or blow a head gasket. to give it an A/F of 11.5, which is richer than what i have now, i would lose power, not increase it.

...right?

Yeah, 11.5-11.9 is pretty rich. Ideally you want somewhere around 12.8-13.0:1. I would leave it a tad rich cuz once it gets colder outside it will lean out a little bit.

Re: dyno graph of 245rwhp

I guess I've always ran mine rich do to the AZ temps, when I ran my supercharger It was at 11.5. Now that I run nitrous I run 12.5 N/A and 11.8 on the nitrous. I'd rather be rich then lean I guess. Thats just my taste.The dyno looks like you were at 12.5 then went down to 12.25.
WHen I first had my car dynoed with the FMU at 8 psi my air/fuel was below 10:1 and it still put out 281hp / 303TQ.

Whats up with the notchy graph? Does it need more tune? The A:F looks great, but something doesnt seem right with the back and forth curves...

I asked the tuner the same thing when I did my car and he said its usually something in the dyno or the computer. Its not a bad thing or something that will mess up tuning or results, it just happens.
