Testimonial Nissan Reviews

Nissan X Trail 2.0 dCi 170 bhp Diesel

Posted on 18th April 2019, 14:45

Had my X Trail remapped at my local Celtic Tuning agent Wow, what a difference. It felt like a different car; much smoother and more linear acceleration and fuel economy has improved by around 3 mpg making nearly 48mpg.

Can only express my thanks to the agents in Suffolk. Oh yeh and best of all my insurance only went up by £30 which included the policy change fee!!

Visited the dealer in Suffolk for gearbox, diff and transfer box oil change and then a re-map.

Considering my car had 162k miles on it the engine was a sweet as a nut but I felt power delivery wasn't all it could be so over to Kevin the technician. After about 40 mins all was done and time for a test run.

All I can say is I was amazed not just at the difference in performance from 173 to 221 hp but how smooth the delivery is; lazy in a way and saves gear changes.

Can't recommend Kevin enough and only 50 mins away from me

I had my LHD Pathfinder in the UK, so I decided to get it remapped.

Celtic did an amazing job. After remapping it I had a turbo problem (not related). Celtic went above and beyond to assist and ensure I was not left stranded.

It turned out there was a blocked oil feed pipe to the turbo that had been there for some time. Once that was repaired the remap could be explored properly. A great job and the extra power is really noticeable. This was just a stage 1 remap, and I can't see why you would need to go any further than that.

Thanks guys! I'm on the way in later today with the Audi TT for remapping now. I can't wait to try that one out on the Autobahn in Germany next week!
