4l80e and new engine tune?

So I have a 02 rcsb 2wd, and i put a 4l80e and am attempting to a turbo a 5.3 bored and stroked to a 6.5. My question is what file do I need to start with in order to begin tuning or even just to get a start tune so I can idle it before i bring to a dyno? I have hptuners too.

Will it not start with the base tune?

Your going to bore and stroke a 5.3 to a 6.5? I think the cylinder walls are going to be paper thin and yeah

+1. if you're planning on 4" bore or bigger, use a 6.0 block

well I was going to but I had the walls sonic tested and they are about the same thinkness as a sbc bored .030 over, lol, crazy huh! but ya my next build will be a 6 liter base. so as far as the start tune goes..... cause its a stock 5.3 tune right now.
