LBZ Tuning

Hey,

I recently did a read on a friends LBZ that i believe was originally tuned with EFI live. The tune seems poorly made to me but I'm having a hard time learning with the missing details in the stickys. If anyone wants to give me some pointers I'd greatly appreciate it. The fuel pressure table has a bunch of less than stock values which makes no sense to me. I'll attach the fuel pressure comparison table to a stock file.

I thought EFIlive changed operating system, no? (So HPT cannot read an ECU with the EFI OS?) In full disclosure, this is simply what I've read/understood. I haven't used it myself.

I've never had to adjust fuel pressure tables, and unsure why one would unless its something to do with injector swaps?
