We have countless happy customers in Hampshire.

IRemoved limiter and remapped ecu for my Citroen Ami by post. It's transformational and makes it so much safer to use on UK roads. All done by post and super efficient turnaround within a couple of days, start to finish

Matt is a genuinely great guy. He did work on my transporter and S-Class, delivering noticeably better power and fuel efficiency. I couldn’t be happier and wouldn’t hesitate to recommend him.

Great service. I had a hydrogen carbon cleaning on my 2008 A5 3.0TDI with 87000 miles. She had no problem just a maintenance. Driven the car in first time I haven’t fill any different but the second time I was much impressed. Smooth start and run with cold engine. Like a new car. The job was Professional from start to finish and Mark was very friendly. He called out at night and done the job next day. Very big thanks! My van coming next just let me coming back from holiday :)

Did stage 1 on Mercedes cls350. The difference in mpg is astounding, even on short journeys The green economy bar seems to be coming on all the time.

On the rare occasion my foot is slightly heavy, it requires much less pressure Absolutely brilliant. Came to my work to do. I recommend Mark and AMTuning without reservation. First class

Popped over to AMTuning today. With both our cars my 1.6tdi Rapid and the Fabia 1.4tdi for remaps. Mark was a top chap very professional. installed the maps. While I went and had a big Mac! Both cars pull really smoothly now. Mpg seemed better just on the trip home!.. engine note on the fabia is lovely too. Very pleased. Would recommend any one with a VAG group diesel to Give Mark a call.

Mark remapped my Audi (engine and gearbox) and it is like driving a totally different car - almost a 60bhp increase. He was informative throughout the process and when we came across a small glitch he sorted it straight away. Really nice company to deal with and the service was top notch - I would highly recommend Mark and AMTuning.

Had my audi A4 avant remapped today and before getting it done I was sceptical i would notice any difference! But wow what a difference! Im over the moon with the results! Also what a lovely chap! I'll be recommending coming here to everyone I know!

This is the third car Mark has done a remap on for me and yet again has not disappointed. Much faster acceleration and fuel economy. I also had a hydrogen engine clean to clear all the carbon build up which has made a massive difference in performance also. Mark’s always on time, friendly and trustworthy. Highly recommended and will continue to use him.
