More fuel out of a CP4?

[gmduramax]

Are there any tricks to get more fuel out of a LML CP4? Has anyone played with the FPR?

The tuning can get some more with h&s's mcc stuff not sure about efi but if you want more a modded pump or dual cp3 kit is best route imo

The truck has Kory's tuning. On the hot street tune 170hp it drops rail down to 22,000. And that's with an Airdog 165 with the pressure cranked up.

Does anybody sell a modded CP4?

Industrial has a modded cp4 but the hassle it is to put a cp4 in isn't worth it plus cp4's have a reputation of not being so reliable. Adding a cp3 to the stock cp4 is the way to go.

Really I had a truck with korys 170 tune no lift pump hold 28-30k lol thing is freak you sure all your fikters are good and airdog is pushing fuel

I know the airdog filters are good. I'll have to put a fuel pressure gauge on it and change the factory filter.
