Well it was empty when we started and it has pure C16 in it now. So we will have to run that out, or we could just turn the boost back down to around 18-20 psi which is the max we are going to recommend on pump gas. As you may know the racefuel isn't creating more power, it just allows us the flexibility to run more boost without hurting the motor. It would also allows us to run more aggressive timing and leaner A/F ratios. However this tune is using a 93 octane timing map and the A/F is 11.5:1 which is OK for the pump gas.
Regardless if it has pump fuel actually in it or not the numbers are going to basically the same. It would make these same peak #'s on pump fuel if you really weren't concerned with it lasting a long time.
This car has more in it if tuned to the edge taking into account the race fuel. I'll try to get a chart posted at 18 psi in a few days.
