Has anyone had one put on?

My friend/ mechanic has started doing them at his garage and for a standard 4.2 supercharged, the power increase is listed as 54hp and 90nm of torque.

I have already had my supercharger pulley upgraded so... Noisy black one

Afternoon all,

I have just had said remap done and it’s great. More power, greater economy and more noise. 500hp will keep me content for a week or two. Noisy black one
