LBZ FPRV

[BoostN]

For the guys with the basics, trans, lift pump, and big tune. Do I have to worry about "Shiming" my FPRV on my truck?

I'm finishing up my lift pump today, so my only worry is popping that open tonight at the track.

if you have the time and parts i would change it, or wait and see. some pop, some dont. i dont think the lbz is as prone to it as the lb7/lly.

I don't have either right now. I still have to change the oil on the fuel filter before I go, and finish the AirDog.

We will see if it holds!

It's not a bad idea even if it's not giving you any problems yet...

I don't have it done on my Truck.

Thinking about it, but I haven't Thrown any CEL's for Rail Pressure, ever, so I'm not too Worried about it.

After the limp pump got installed and me running down the track a few weekends ago, no issues yet. Hopefully I won't have any.

Chances are you won't have anymore Issues now that you have the Lift Pump.
