    09 LY5 5.3 Top End build tune needed

    I've recently completed the top end build for my 2009 Tahoe LTZ RWD. I'm in desperate need of a tune. I have mpv3 and the credits unlocked but I have little none experience. She's running like shit but did start up. I haven't ran a scanner yet but i know she's miss firing on all Cylinders. I'll list what's done below. Anyone with a similar tune file please let me help. I just need to get it to the dyno. Willing to buy a tune for the right price. No scammers please.

    I figured. I'll do that today. I can't drive it cause it's running to rough. I'll get a base and upload it

    what i always do is get it to idle first then you can kinda get an idea where you need to be. Once we got that down we can go back and make those adjustments.

    Did you disable the AFM/DOD first before trying to fire the engine up?
