My 120% over lbz pump will be here Monday and I will need to rescale it. I know what table it is but not sure what needs changed?

B1010 table. Copy the lly b1010 table and paste into your lb7 table and it should work. I know this works for a stock pump, not sure if it's any different for a 120% over. Hopefully this helps.

Would have never thought to use an lly table for an lbz pump but I sure will give it a try. Thanks for the help

Who's pump? Stock regulator or modified?

Its an II pump. I believe they modify the regulator. I'm currently running an lb7 pump with an II bag o parts. I never made any tuning changes for that moded regulator. But the regulator was for an lb7.

I attached the picture from Fleece's website. This is the table they have posted to use with their pump/regs so maybe it'll work. There's also a write up on Fish tuning. But those are for lbz regulators, you might be able to put your modded lb7 reg in and not change anything.

Yep, have done several that way. Works good. You'll also have to bump up your pressures to get it up to 25k. If everything works right and you get the psi up that high you'll prob throw a high psi code and limp your truck. P0088, disable it and you'll be fine :)

I appreciate all the info I should have the truck running again in a few days to give it a try.
