Pro Racer users running higher base pressure

[MysticDan]

What if anything needs to be done in the tune. 80# SD injectors with a base pressure of 55psi. E-85 fuel, stock mass air with a mafia on setting 3.

I did scale the maf table,injector values, and displacement as required by the mafia. Stoich was changed as well.

Do i scale displacement or injector files or neither?

Im going to assume return style fuel system? if so then i think that's all that needs to be done.

 

[MysticDan]

Yes it has a return fuel system.

 

[MysticDan]

Anyone else have any input.

If you still have the FRPS installed and functioning, then you can change the fuel pressure (using the FPR) all you want and it will not require any changes in the tune.
