A performance map from a tuning company such as SAWS or Force Tuning can get you closer to the "160" number, but it's not possible to hit with the stock turbo, you run out of boost. With a manual boost controller set to 24psi you can hit just shy of 155bhp.
Fit a bigger turbo and you will then be limited by the fuel system to around 165bhp.
I've said time and time again that a dyno run with video and printout proof should be done for this map. There is some sketchy evidence that is an excel spreadsheet showing that a car hit 170bhp with the map and a synergy box, but it is simply not possible because of the mechanical limitations.
There are a few people that have gone from a "160" map to one that maxes at around 155bhp and they have noticed a significant performance increase. I wonder how that is?

Thanks Jamie some useful info there.
