I have 2 x TID's Wagon,Vert(autos) and Saloon(TD 8V manual) all custom mapped.
EGR closed,swirl flaps fixed and tweaks to minimise the hesitation at low revs before the turbo kicks in etc.DPF is not disabled and I monitor routinely with the android app DPF info.
They can easily be mapped to 180-200bhp with little effect on mpg.
I routinely get >50mpg fully loaded with top box on a long run dropping to 35-40mpg around town.
If you are in the UK drop me a PM and I can send you details if your are interested.
BTW 150 to 160bhp will hardly be noticeable......if you want longevity with the car its important to sort the EGR,swirl flaps and inlet manifold.
Some remove the DPF completely and push the car toward 250bhp but with the latest MOT regs its just not worth it.
