Default LBZ regulator - EFI Live

What all do i need to do to run an LBZ regulator in my LB7?

Through my searches i have found there are a few tables that need adjustment but i was unable to find which tables those were.

Another question - Is it worth it to run a LBZ regulator over a LB7. Mines shot in my LB7 and i have a brand new LB7 and a brand new LBZ.... Figured i would run the LBZ but just wanted to make sure before i install it with the new injectors.

DirtyDemon/CodeRed is getting some more work done to her this week :-)

Ive never really heard if anyone has successfully installed one due to the 90* of the newer regulators?
Some trucks dont even need adjustments for the regulator

No changes, but you must relocate some plumbing to run an LBZ regulator.

I'm getting a few more LB7 regs made up, but they are harder to get and cost $20 more than LBZ ones.

I'm almost tempted to heat one up with a hair dryer and try to bent it straight.

That might just work or maybe just cut the end off and solder some wires to it? Kinda ghetto but.......

If you plug the regulator in before you bolt the hard line down, you will be fine. There is plenty of room there that nothing touches when you are done. Just be sure to have the other end of the line/ banjo bolt started or you will be taking the line loose and the banjo bolt out again. I have had no problems doing it this way.

didn't unbolt the hard line - i plugged in the connector before i bolted the regulator down. It clacks like crazy at idle. loaned out my tech 2 for 5 minutes - we are now going on 3 hours that it's been gone.... gonna check things out later....

once i get my license for efi i will check things out and mess with them.


First impression-LBZ reg is nice. I gained a lot of power !

Could have been because the old reg would only make 117mpa

Overall it was an easy install no modifications at all.

gonna need to do something with this idle though - she's loud !

Thats not too bad, i have twin modded lbz pumps with modded lb7 regulators, when i first put them on it would idle at 23k lol it was horrible, you can adjust the voltage under the rail pressure valve current. I just took my whole chart up 15% and it took the rattle out and now it idles around 5k with a slight lope.
