Default HPtuners: IFR vs KPA for 72lb/hr injectors?
just like the title says, what should my ifr vs kpa table look like with RC 72lb/hr injectors?

Should be a flat 72 or 9.071848 if its in g/sec, since you have a return fuel system, and if your injectors are rated at 58psi

72 or 27? you are reverting back to the stock injectors, right?

I assumed the 27 was a typo since he said they are RC's

I spoke to rich from w2w today. He has it set at 39.xx on purpose. something to do with it being 2bar sd and having to trick the computer. all over my head. i was just curious.

Thats bad news, that means they didn't do a custom OS 2 bar operating system with it and just faked it. IMHO, thats not a good way to tune for a supercharge.

Ya that does stink. They mean they took a calibrated set of injectors with known values and manipulated the values so the computer will run the appropriate AFR
