Testimonials:

Mercedes E350 CDI Galleywood Chelmsford Essex

Mr. Colebourne “Cant thank Anthony enough for the excellent work carried out on my vehicle. I went for the works! Full performance remap with DPF and EGR removal. Car is really responsive with none of the turbo lag I once hated.”

Range Rover Sport SDV8 Stock Essex

Mr and Mrs Wood “Extremely happy with the service that GAD provided me and my wife with. The beast is a little “juicy” so Gary recommended a blended performance/economy map. So far so good, the power increase is lovely and have seen a 4 MPG increase and I didn’t have to leave the house! We took advantage of there free collection and delivery service and didn’t even have to leave the house as William came in person to collect our car.”

Porsche Cayenne 957 Turbo S Wickford Essex

Mr. Sandford “Many thanks to the GAD team, more than happy with the power I’m sure you think I’m crazy or wanting more power and torque but what can I say? I’m a petrol head and I need my fix of power! Really good job boys!”

BMW 535d M-Sport Danbury Essex

Mr. Woodley “The car has been transformed, I have always been sceptical about tuning vehicles however after chatting to Anthony via e-mail and telephone calls I felt confident in proceeding. The torque is incredible! They came over to my house and mapped the vehicle in front of my eyes and explained the process with me. After the initial test map they asked if I would like to go further and through there recommendations and expertise I had a little more out of it! The vehicle is nothing short of incredible and completely changed my opinion on slow, sluggish diesels.”
