I want to add a lift pump and shim the FPRV valve? will the mods add any power gains?

 

[Meyerperformance]

They will not give you a power gain. But you will be able to take full advantage of the tunes you run. That will make it feel like you are increasing power though.

 

[DSTRBD]

Yes, you will notice a power difference in the mid/higher settings as you will actually be supplying the fuel the tunes are calling for.

I didn't notice a power difference yet, but my truck doesn't cut out like it used to at WOT. I bought a PPP lift pump and shim kit from Nate at performancetruckproducts. So far I'm happy with it.

I've said it before, in my opinion it's always a great thing to have, but you'll never take full advantage of it on a stock tranny. My thoughts are that you shouldn't NEED one until you build your tranny. Because it's plenty easy to grenade your tranny without one.

And I wouldn't bother with the shim until you start having problems.

Alight thanks for the info, yeah the truck feels slugish when i shift into fifth...Yesterday a stock lbz 4wd with flaskpack chip set on performance 6sp lept upwith me pretty good, i we called it a tie. I need ya's opinion, i have a lmm MP and im putting a airdog lift pump on. will the MP help? and what do i need to install it?

 

[05greendmax]

ok all youll have to do to install the mp is cut your intake tube and make sure u measure 2 cut once

it wont do any hp gains just it will supply the right amout of fuel the motor wants
