It'll do 1.5 bar, but it'll kill the turbo.
My advice to you is;
Delete this "stage 2 tune" and don't look back.
Pay a real tuner to make you a proper tune.
Alternatively, use the free resources on this forum and make a tune yourself.
Even you could probably make a better file than this in a relatively short time.
I'm not just ripping on you/this "tune" for some sense of satisfaction.
I'm stating the facts, and helping you understand how bad this "tune" is.
If I told you the company that sold me this tune you'd seriously be shocked.. Ok, for now it will have to get me about. BUT I taken all of what you have said on board.. I will look into sourcing another..
I will use the map pack that was kindly uploaded on here and look to improve upon the file. I will use all the info I can on here to build a better file...
I can't thank you all enough for your help.. I'll stick around on here!
