It's also drinking a LOT of fuel from 2500rpm onwards.
Mods: 2 1/4" pipe exhaust, Mid silencer removed, SuperSprint Backbox (125i twin tailpipe look), GFB+ Diverter Valve, Pipercross Performance Air Filter. Car has had a full service recently too.
I'd like some advice on the hp gains and torque loss from the dyno run (link below). It looks wrong, before torque was almost constant from 2300-4100rpm which seems okay. But the torque after remap just keeps going down.
-------------------------------------------------------------------
Standard
Hp: 148.8hp @6391rpm
Torque: 196.8ft-lb / 266.82Nm @2721rpm
After Remap
Hp: 216.4hp @5876rpm
Torque: 275.5ft-lb / 373.52Nm @2866rpm

I'm planning on going back to them. Those that have already got their remaps and dyno's, share your experiences. If possible, upload too.

This does not seam right at all...
especially with the supporting mods, my car transformed with just stage 1 no mods and now i have almost gone stage 2 with inter cooler, m135i spark-plugs and m135i ignition coils i cant wait to get it stage 2 tuned.
it sounds like maybe your running rich (from your fuel usage and no torque)
this could also be your spark plugs!!! but i very much doubt it due to your recent service unless they didn't replace/check them ??
either way i would suggest upgrading to some NGK or M135i spark plugs.
much better down the line.
another thing, have you checked for boost leaks?
