OK, I will check timing. Good thought. Haven't dug that deep into the car yet, as it runs quite smooth. Thx
(as context, I am still on the previous tank of gas from when I purchased the car, as it was almost full) I do use max octane pump gas, though in AZ that is only 91

I have spoken with the engineers at RP, and he told me that I can use 2 cans for 20 gals, and that maximizes the lift in octane that I will see (so I am almost at 95 with 2 cans, on a base of 91). Pricey, yes. However, I do not fill up all of the cars all of the time, so it is tolerable and helps protect engine and maximize performance. For those interested, O'Reilly will give you 10% off a case if you purchase that amount. On occasion, you will find RP Max Boost at O'Reilly on sale for 10 something. Its a great deal.
So, if I am running 94 equivalent in the GT (with Paxton), what is the target advance I could target, all in? Assuming that somewhere between 2500 and 3 grand should have me all in?
Thx
