You are not 21-22 over stock timing! Stock timing is 20 ish bud. Yes you have several degrees of advance left and lotsa power on the table left. A/F looks great though

Ok, good to know. If you ever have worked with Torrie, the exact details are not disclosed.
When he says 21-22 for timing, maybe he should have said +1 or +2 advance over stock. I know the engine has a very inefficient combustion chamber and would need additional timing if the fuel stays rich enough. However, if what you stated here is overall full advance on a stock engine, it sure cannot take much more on 91 pump.

I agree with you on the overall A/F. THAT is where its at on this engines tune. Even stock they are pig rich. Torries drop in tune was 10.9:1 @ 5.5K for 91 pump even after installing B&B, BBK and K&N etc. No wonder I lost .2-.4 seconds on E.T. after dropping in the tune. Trap speed was also down.

Thanks for your feedback.
