OK, so your engine is the slightly lower torque one with the 5 speed box.
I'm sure you know, but if you have deep enough pockets Darkside will get anything you want from the engine.
I personally wont go as far as that, unless (touch wood) the turbo goes pop. Black Smoke do have a higher power map which should give me an extra 15bhp and 15lb/ft which I may look into once I have the Milltek downpipe and possibly Darkside's uprated SMIC.
