Tuning question........

[Brent]

On the dyno I had a minimum A/F ratio of 11.3 and a maximum of 12.9. The average was 12.4 throughout the pull.

Is that a perfectly safe A/F ratio or can I go leaner and still be safe?
That was with 116 race gas and 18 psi of intercooled turbo boost.

I ended up with 602.8 RWHP and 740 RWTQ on that session.

Thanks for any recommendations, Brent.:confused:

11.3 is really fat, 12.0 is good and 12.5:1 is max power.. so you might want to clean up your areas in your tuning where you have 11.3:1. Was that on the top end or where?

The 12.9 was at 5500 RPM's and the 11.3 was at 2900 RPM's and in between 2900 and 5500 was the 12.0-12.9 ranges.

Thanks for the reply on this. The dyno operator wasn't for sure if I was maxed out on the A/F side or not. They just hook up your car and let it rip without any tuning, you do the tuning yourself.
