5.3L Whipple Install fuel pump suggestions

[992dr]

Model of truck is 2002 Yukon Denali 6.0 LQ4 with the Whipple 2.3l with cam, roller rockers, ARH longtubes, 2800 rpm FTI triple disc billet converter and Performabuilt level 3 4l60.

That sounds like a fun combo. How do you like that trans with the FTI?
I miss my 2dr, it had a FLT lvl v built trans and billet yank and that made such a difference. Really made it fun to drive.

It’s awesome. I have broken the trans twice by unknowingly plugging the servo passages with RTV when changing the fluid and filter and I used it on the pan gasket which I didn’t know was a critical mistake. I noticed the 1-2 shift was slamming. The first time, it hit so hard at a WOT pull from a stoplight (I’m AWD and it doesn’t spin the tires) that it grenaded the hard parts. Performabuilt rebuilt it under warranty for free but couldn’t explain why it did it. I guess they didn’t see the RTV. Then a year later I once again did the fluid / filter after break in and shortly after it twisted the output shaft in two. I sent it back and this time they saw the passage blocked so the servo wasn’t releasing. They rebuilt it again for free even though it was a year out of warranty. They’re stand-up guys. The thing shifts amazing, hits hard but not too hard now. It used to shake the whole truck lol.
