All depends what you want Ian, a very easy 270bhp is achievable and a bit more boost and fuel pressure can hit 280bhp. DPF's are the big one. Would massively recommend getting rid of this after a while and I can program it out. Beauty of that is more power and fuel economy due to the massive restriction.
All my maps are 7 day guarantee anyway, if you're not happy come back and I will put you back to standard.
I do all my own maps so can give you exactly what you want. I've owned 3 x 3.0 TDi's and know they very well
Give me a call sometime 07728 835500 (Think you have it anyway!)
