What is everyone using for a PE ratio, I have mine set at 1.33 (roughly 11:1) and have heard this is too rich. What is an acceptable afr for 10-14psi on pump gas (will be using meth when the weather warms up).

Also, is anyone using the boost enrichment in HP Tuners. What is the advantage of this modifier vs. just using PE?

Its benefit is to have different commanded AFRs at different boost levels. 11:1 is just fine above 10psi on pump gas.

Keep preignition out of it, and that AFR is fine.

PE is just a number, it tells you a ballpark, but thats really it.

Id like to see it in the 11s on pump, and no leaner than mid to low 12s on race fuel.

Make the power with spark, AFR doesnt make a big difference like spark does, just watch your plugs and keep up on the tune up.
