Upping RP

I was just curious if anyone's messed with RP on a stock fuel system? I bumped RP to help with haze at idle to 7k and it seemed to be a bit snappier with the throttle, would that be the case through the rpm range? Any side effect to doing so? I'm talking just bumping it 500-1000psi across the board, any input . Thanks

Shouldn't hurt anything

From what I've found the trucks drive better and less smoke if you basically make the throttle respond off rail pressure first. So the faster your rail comes up the better. Pw Will stay low and once rail comes up then Pw will come up. Should work good keep messing with it

So just ramp up the rail pressure across the board? I should keep RP at the top end the same right? It's says at max throttle that it's commanding something like 24,880 psi, I shouldn't increase that right or will it not hurt

I have some tables commanding 26k or 28k im sure. But im nowhere near my computer to see for sure what the highest is.

Correct, just ramp it up sooner, you can try for a little more rail like 27k if you want, if your on a single stock pump it may not make the full 27k

Ok I'll try to up it. Thanks guys
