turbo 5.3l gen4 SD or run MAF? Hi guys doing a lh6 gen 4 s476R turbo into a 70 c10 i know the gen 3 guys eliminate the maf for boost is then gen 4 the same? Im ordering ecu, harness at tax time so wondering if i'll need the maf or not?

From what I'm reading, it depends on your intended boost level and intended driving purpose. If it's to be a Daily driver most of the time and if you're staying conservative (8psi or so) then the MAF based might give you better mileage/drivability/civility. If it's going to be a warhorse or a weekend warrior, then SD time!

What will you use for tuning? Do you have HPTuners or EFILive?
I have HPTuner pro, a couple of Wide bands and a tuning book, so I'm pretty dangerous (to myself
). I will be getting a pro tune on a dyno to start with but will fine tune the rest myself. The book, "Master EFI Tuner - GM EFI" by Dan Maslic portrays how to setup your LSx engine for 2 bar Speed Density and it seems straight forward enough, if you're familiar with the interface(HPTuners). But knowing myself, past experiences, I'll have spent way too much money on the engine/fueling/chassis to risk making an unforced error on the tune.
