i was going to install my new fuel pressure regulator on my truck this week but was wondering if it would ran like crap untill i got it tuned w/EFI since it is for a lbz. id have to drive it to the guy who is going to tune it since my buddies v2 is broke and will have to by a new vin. any advice would be great as to i have no clue how it will act when installed

Its driveable but will idle with a huge lope, I have LBZ pump and regulator. I put a tune in with the stock b1010 table on accident which is what will need to be changed, it loped so bad it died after a couple seconds. I wouldn't do it unless you have EFI live on hand.

i can install the lbz regulater in the lb7 pump and get better flow correct? i shouldnt have to do the lbz pump rite?

Yes you can put the LBZ regulator on the LB7 pump and it flows more, they are identical on the outside of the pump other than the plug in on the regulators, the LBZ regulator plug in has a 90* bend on it so its a little tighter fit.
