It's the edge of danger. 11.5 is better on 93oct, but you can tune for 12-12.2 on race gas, depending on the octane.

I dont even tune my race car at 12.0 / 1

The amount of power you gain at that lean a/f ratio is not worth the increased risk of harm

Generally I tune for a nice fat 11.2 / 1 a/f

Yes - let me know what time you want to come - we are open on the dyno that day from 10:00 a.m. till 2:30 p.m. - it takes me about two hours total to do the dyno and tune

Note - the dyno is at www.pruvenperformance.com in Milford, CT
