IMO unless you're doing something way out of the ordinary (K, J, Frankenstein motor) then just get your ecu chipped (as long as it's obd-1) and don't waste your time spending extra money on other fancy programing.

What is your horsepower goal on this project?

not sure yet my base map is tuned for 11lbs and was watching some vids of stock ls on 10lbs make 269, i dont really have a goal atm, i just dont wanna be the slow one in my crew and be faster than this dbag i know lol XD but it didnt get finished today tomm for sure ran into another prob. Also when i take a vid how can i upload it off my camera, like do i have to use a site or no.

I was just curious due to the turbo you are using. I made a few calculations for you using the largest GT15 that Garrett offers, the GT1548. I calculated the peak necessary flow rate and pressure ratio required for 230 crank horsepower (200-210whp) on that turbo.

I'll save you the headache of looking at the math but I will tell you that your airflow target is way off the compressor map, far past the choke line.

Just letting you know that you should care.

You do realize that a turbo operating past the choke line will die very quickly right? Garrett defines the choke line as where the turbo goes less than 58% efficiency. Past the choke line, compressor speed increases exponentially approaching it's limits. Considering how far you will be landing outside of this boundary, that turbo will work better as heat pump than an air compressor.
