Re: Doing LS Swap - I have no idea what I'm doing!
You have a 5.3, see here. https://sites.google.com/site/sloppy...a-4-8-or-a-5-3
Your tuner should be able to flash in anything he want's. The 4.8 and 5.3 use the same ECM, just the tune is different. I would verify your injector part # and give him that info and just let him flash in a 5.3 tune with a little more timing and turn off security and the rear 02's and go for it.
