Across the board really but lets say pump only for this.
On pump only I target richer than 12's lol. Lets see:
-ACN91 with high boost: low 11's
-Race gas like C16 or E85, DI only: high 12's or low 13's depending on boost like 12.7:1 to 13.1:1, unless you live in Germany
-E85 with PI: mid/low 12's depending on how much PI
-Pump with meth: 11.8 to 12.2:1 depending on situation
-E85/race gas with meth: high 12's low 13's
Going leaner into the 13's works fine with DI if you have good octane but when you start adding things like PI and ACN91 into the mix, DI isn't going to save you from knock. A little richer is a bit safer as the EGT's get cooking on long pulls too so it's something to keep in mind.
Would you tune exactly the same on a PI engine?
Sadly 91 ACN, my meth kit is pretty solid. Good pump, all steel braided, solenoid keep system pressurized and also running injectors.
Man, I feel spoiled here in upstate SC. Got e85 stations all over the place - hurts to read about folks in other parts of the country that don't have easy access to e.
