I've got a 2002 LQ4 engine that I'm swapping in front of an old non-computer controlled trans and need some help with tune or figuring out what initial tune to load. I've heard I can use a Silverado 2500 6.0L Manual trans tune but I can't seem to find one for TunerPro (.bin file)

Here's what I've got:
2002 LQ4 engine from Yukon XL - Cable Operated Throttle Body
2002 Wiring Harness, Thinned out and removed the Trans components, and the rear O2 sensors
2002 Mass-Air sensor and intake tube from the Yukon XL
411 PCM from a 5.3L 2002 Silverado with a 4L60E (someone snagged the 6.0 computer before I got to pulling the engine... If I can find one of these would it be a better starting point than the 5.3l tune?)
Trans is a TH400 right now and if I get serious with the car I might go to a transbrake powerglide...

I'm turbocharging it so eventually I'm going to run 8-10 PSI boost through it but right now I'm just wanting to get the engine running in the chassis and everything hooked up before bolting the turbo on and fabricating the intake plumbing.

SO: What parameters do I need to disable or enable or change to get an acceptable tune? I know I can go through and just blindly change all the auto trans calibration stuff but that's really not ideal...

I think you're in the wrong section, this is diy prom,(the ecm sub section might know more about the obd2 swaps, it one down from this) as in older obd1 ecms with chips. sounds like you're trying to do a sloppy mechanic build. check his YouTube and site. you'll need hptuners to flash the 411 ecm. but he's got everything you need laid out for turbo junk yard ls builds. should even have a starter bin. the ls world seems fun, but also the rabbit hole is very expensive. I tend to just leave them stock in my cars that have them.

good luck with it.
