I will be tuning with my Wide Band this weekend for the first time (been on a dyno before, first time tuning myself)

I know the same A/F is not optimal for power & safety so I was kinda looking for a safe combo of both, with a few questions.


Do you risk detonation at higher RPM rather than lower? or is it all boost related. I hit max boost by 4K, should I run just as rich at 4k as I do at 7K? or can I run for a little more power at 4K (leaner slightly) and run safer at 7K (richer)

I have 2 stages of boost, First stage will be 8-9 PSI, second stage will be 12-14 PSI. How much richer should I run in my scond stage of boost? I assume that risk of detonation goes up based on boost do to more intake heat being created? is this an accurate asumption on my part?

My thoughts right now are

11.3-11.8 ish at low stage of boost around 4K, leaning closer to flat 11.0 at redline on fist stage of boost.

11.0-10.8 ish at 4k on high stage of boost, getting closer to 10.5 by redline at 14 PSI ish?


how does that sound? too lean, too rich? Or shoudl I have a flat level all the way no matter the boost & RPM?

opinions appreciated.

The area around peak torque is where it should have the richest mixtures and the lowest ignition timing.
That's normaly in the 6 to 7k rpm's depending on porting.
My motor took the most fuel around 6500 rpm.
Crispeed did my tuning so he would better be able to answer this question.
