I see a lot of guys running LBZ FPR's on LB7's and LLY's. What is the advantage? What tuning adjustments should be made?
Thanks.
Thanks.
LBZ FPR on LLY
- Thread starter DuramaxTireSmoker
- Start date
The LBZ FPR is supposed to flow more than the older ones. I don't think its much more, but every little bit counts. I put the whole LBZ pump on mine because my old one couldn't hold rail pressure any more. The tuning needs to have the regulator current changed to get the pressure control right at low rpm.

More flow. Adjust the low ranges of the B1010 table until idle is smooth, otherwise you get an annoying lope.
If you are spending the coin to do that, you might as well upgrade the fuel lines from the tank up to the CP3.
Where can I find a kit to do that? FPR needs replaced anyway so I wont be spending extra money.
I added a stock LBZ Regulator to my 30k LLY pump... I held 22,000-23,000psi all the way down the track. According to my logs my RP would spike to 25,000psi for spurts as well
What was it holding with the lly fpr or did you try it before installing your pump.
lot of people that did this swap gained a 1000 psi min on there rail press
Ordered an LBZ fpr. Hope I can figure out how to tune it
add 50 to the top 3 cells of b1010..... if it still lopes a bit add 25 to the top 2 cells untill the lope is gone

This explains it in detail how to get it as exact as possible, running smooth without any spikes in pressure and whatnot. Good little tutorial.
