Had my 2008 Kia Sedona in for a Hydroflow a few weeks ago because the fuel consumption was terrible on it, also took several seconds before the turbo was kicking in under acceleration. Credit where it's due, the turbo kicks in almost instantly now. As for the fuel consumption, I did just over 200 miles on the weekend and there was still half a tank left, whereas I was lucky if I got 300 (motorway) miles out of a tank before. Good work ARC! �

  Just had the Skyline on the Hydroflow. A definate improvement all round. Well worth the money. Thanks Guys.

  Had a hydro clean done by Tina, very impressed with the results and the service in general. Will be using again and would highly recommend.

  Can’t recommend the dyno days enough, great atmosphere and the guys do a fantastic job.

  Amazing service and lovely people to talk to. 100% recommend for MOT repairs or little things you need doing to your car �

  Our recent trip to ARC with 6 cars for a dyno day was professional, well organised and the whole team were very accommodating. All cars were well looked after, inspected and warmed up prior to power runs and handled with care. The service is exactly what car enthusiasts are looking for and I will be sending many others your way in the future. Many thanks to Tina and the team!

  I recently had my Audi A3 2.0 TDI in for the Hydroflow clean as it was very smoky at times. I was advised that the Hydroflow clean would improve this. I have seen a massive difference since Ive had it done and have only noticed a small amount of smoke on the odd occasion. I have also found that my fuel consumption has improved. Would highly recommend it. Thanks to Tina and Andy.

  Very friendly service, thank very much, Tina. Our Kia Sorento had a Hydroflow today and is like a new car. Feels just like it did when we first had it. Going to recommend to our friends and family.

  Brilliant friendly service. Had a fantastic time at the dyno day and saw a huge range of cars take part. Not only that, but I often go to them for advice. They took great care of my Pontiac and got her running better than ever, keeping me updated all the way through and never minded when I popped my head in the door. Will be looking at a map for my Megane 225 through them and despite moving soon, will still come back to them as my garage of choice for tuning, repair and MOT for all of my cars. Thanks again!

  Super professional service with fab results! I had the a hydroflow and a remap on my new car and I'm so in love with the results. So much so I'm making my dad and hubby have theirs done too ������

  I've been to see Tina at ARC dyno tuning to get better fuel economy on my Peugeot 206 hdi since being done I have found my Peugeot more lively and fun to drive. I highly recommend as I've had a brilliant service � Ps I will see you in the summer for a dyno and check over. Thankyou

  Had my 09 c4 Picasso in for hydroflow treatment this morning , didn't really understand until Tina explained what is was about so left my car in very capable hands � Had a call an hour later saying it was done , when I got there I had a quick chat say it didn't feel much different but after the drive home back to cirencester all I can say is wow !! It's so much quieter and tickover is a lot quieter being a turbo I was worried about that but you can really feel the boost and it breaths so much better , no black smoke and runs on lower revs now so should save on fuel which will show over time � Great process and well with the money my car feels like a brand new car after this ! Thanks a lot �

  I took two cars for a Hydro Flow today, and have to say after pulling away after the Hydro Flow, the performance off both cars is fantastic... it's as though they are brand new. Will be highly recommending this to family and friends. A great job done by a very professional company. Thank you Tina and ARC. ���

  Great service, friendly and willing to go that extra mile to help when you need it

  I had the HydroFlow treatment on my Focus diesel recently after noticing a slow decline in the mpg, and receiving an advisory for emissions on the MOT. I was a little dubious before the treatment, however afterwards it was certainly noticeable. The car has had an increase in the MPG, bit more noticeable is the feel of the car especially an increase in throttle response and lower engine revs both idling and while running. Would definitely recommend!

Thanks to ARC for letting us use the Dyno today. A great helpful happy team.

  Awesome service and an awesome team. My car was runing terrible before they tuned it for me and now have more power and a bigger smile.

  Great service and made the car much more driveable and responsive without changing the good characteristics of the engine. Very pleased, thanks Tina and team
