Hass Performance

Been a few other tuners in the Glasgow area in the past but found these guys to be far better. You get straight up honest answers to your questions and the owner has a real passion for his work and cars. If your looking at getting re-map or even things upgraded brakes/pads or an exhaust etc, then you really need to check these guys out.

Used many tuners in Scotland to remap my vehicles, this by far has been the best remap. Incredible power gains, improved fuel economy and a beautifully smooth power curve. Would recommend before any other tuner in Scotland.

Great garage , always helpful and friendly , unique and exclusive work done on a few of our cars. Very happy with the results , and they are also great at communicating and tailoring to your needs, would definitely keep using them.

Had my c220 CDI in to Hass performance and can’t recommend them enough car got a stage 2 remap and dpf delete and it drives like a new car, pulls like a train! Very professional and great value for money. Thanks again to HASS
