I set up a tune truck runs and idles but for a 2 bar map ive heard to set it up for 200 kpa and 10.33 if I apply those to my tune the truck wont run unless I pedal it to life then once I let of the throttle it dies any help would be great

I am a newbie, so take what I say with a grain of salt.
Have you changed your injector flow rates?
I just put a V2 on my Ls1 with the same injectors and E85.
The 2 bar MAP sensor I got must be a 3 bar, as it shows 118kpa at about 12 pound of boost.
I actually went and got a boost guage because I didn't believe what I was seeing in the scanner.

Because I was worried that I would stuff something up, I did it in 4 steps
1. put the supercharger on, no other mods and started it up on petrol (gas)
2. Put the bigger injectors in, changed flow rates and fired it again.
3. put in 2?? bar map sensor and fired
4. changed fuel pump and added E85, changed tune and tried again.

I think we need to do it step by step like that until we have lots of experience

if your offset and linear is correct for your MAP put the key in On motor off and the scanner will show you a map reading around 100-105 KPA thats Baro presure thats the easy way to check if your linear offset and MAP are in the same page LOL

When you loaded the 2bar OS, did you transfer over the known parts of your VE table?

Yes ve table stayed the same just plugged in linear map at 200kpa and 10.33 offset
