Last August I ran my all time best ET in 1/8, 7.12 @ 95, My data logger showed lambda at 0.89 on that run (AFR=12.5 for E10 gas in Calif.). Since then lambda has increased due an ignition problem and ET has come up as well. I have fixed the ignition problem but lambda is now at 0.94. So my question is, should I rejet the carb to get back to 0.89 lambda? I have been running 76 primary/80 secondary in my Holley 750 DP.
