Hi, all if you're thinking of remapping your Volvo at Celtic Tuning it is awesome to unleash the full potential of your Volvo wish I had done it ages ago. Saving fuel by using higher gears also driving sensible. Celtic can now upgrade your Volvo by the OBD port took 30 mins and it's brilliant.

Transformed my car!

I’ve used Celtic Tuning in the past (10years ago) on my 2.2Type S civic making it a 192hp/316lbft powerhouse and recently my 2006 Volvo S40.

It’s always had flat spots and ran out of puff at 3000rpm, they booked me in within a week and did the work on my drive whilst I was at work, wow!!

It’s completely transformed the car, power from 1500rpm pulling strongly till 5000rpm and beyond! It’s incredible and has made the car so much more drivable, amazing midrange power on motorways!

Very friendly and helpful staff, good honest service I can highly recommend for the 2nd time! Top work boys!!

Got my first 4x4 for winter to carry our baby and puppy around and needless to say I wasn’t happy with the laziness of the 163 XC90.

Booked in a stage 1 with Celtic tuning and Cameron arrived on time and within a couple of hours transformed my car. Torque increase means I am more confident at junctions and roundabouts and the remap means at cruising speeds, it doesn’t feel like the car is struggling. All this with better mpg’s Too.

Thanks guys. Definitely value for money and will recommend for sure.

Not an actual picture of the tuned car

To be truthful, I was a bit disappointed with my XC90 after I bought it. For a 3 ltr engine - all right I know it's a heavy car - it just seemed like a bit of a tank. And I know it is a bit of a tank! Anyway, I was going to Cornwall for the half term and arranged with CT to get the car's s/w updated in Newquay.

Bloody hell!! What a difference. It now moves as good as the Volvo S60 2.4 petrol turbo that I part exchanged this tank for. And yes the fuel economy is better - but 14mpg in town (previously 11!) and maybe 25 on the A303 (versus 21 before tune-up) is still a bitter pill to swallow.

At my age I should be slowing down, but I do like surprising people away from the lights!!! Well done CT.
