I'm running a classic FAST Seq and I'm looking for some info on my A/F Ratio. I made several pulls on the Chassis Dyno and my A/F seems a little lean. I had 13:1 @4300 RPM and about 12.5:1 at 5600 RPM and 18.5 lbs boost. It made good power (581.1 HP/ 543.05 TQ) for that boost but I was afraid to go higher for fear of leaning it out too much. I only plan to go to 24 lbs boost for now but I want to play it a little safe on the A/F. What kind of numbers should I be shooting for.
Also, do you have a suggestion on a backup for the Fast WBO2?
