I actually found some dyno graphs from Promotec.

One of the cars, Mr Arbee is a user in here.
Of course this is on a duno at the company that has done the tune and not at an independant shop. be aware that the numbers are all at the wheels.
After I have installed my DPF removal pipe I will have a dyno at an independant shop that has dynoed my car twice before, once with a tune up and once with a tune up after adding the bigger IC.
