E38 Is giving me a hard time

[nonnieselman]

So after tuning hundreds of 99-07 PCMs i started diving off into the E38 and done several small cam tunes no problems.
Friend of a friend ask me to tune his dads truck after his dad had passed away.
Alot of unknowns about the truck since it was built in the back of the shop and nobody knew about it.
Best we can tell it has a LSA engine with the LSA Blower, Stock lower and upper pulley. 52# injectors.
comp 235/249 .608/.613 116+5 LSA
T42 4L60E with a 2800 stall

It looks like his dad got it to idle and move around pretty decent.

I towed it to my shop to start tuning on it and it has very lean tip in. So im trying to figure out the E38 tuning thing now for boost.

His dad was using HPT so i got his laptop and HPT interface. But i read the tune off with EFI just to see if it made sense to me.

So the HPT tune file shows MAF Calibration Engine>Airflow>General>MAF Calibration. But it doesnt have any type of "VE" table.

I read the tune off with EFI and i see it has the the Virtual VE but no Maf Tables for the Frequency changes like the LS1B and the HPT tune.
the truck has a wideband in it. just have to figure out how he had it wired up.

Now im at a loss and have downloaded all of the tutorials for the E38 tuning and now the fun begins.

Any advise or help is welcome.

Tunes attached if anyone wants to look over them. I have a 10 minute datalog from HPT also. LTFTs are very high.
