    5.3 with 4L80E

    I'm a tuning newbie and trying to learn TunerPro RT. I want to tune a 5.3 with a 4L80E. Since you can't do segment swaps with TunerPro, can this be done? I have not seen a bin for that combo. I've been told I can clone an HP Tuners tune with LS Droid, but you can't change any of the parameters with TunerPro. I want to be able to use my stock PCM without having to use HP Tuners. Any advice would be greatly appreciated!

    I believe LS-Droid is working on adding in a segment swap option.

    Would it be possible to take your PCM to a Chevy dealer and have them squirt an appropriate OS that will already have 4L80E support - simply give them an appropriate VIN for it????? Then do your as required edits inside Tuner Pro RT for the remaining changes that you need?

    Just a noob here with possibly wrong ideas.

    Closest starting point would be a 4.8/4l80E van. Change the displacement scaler, copy the spark, VE, and MAF tables from a 5.3 and go from there. Or segment swap the 4L80E into a 5.3 tune.
