Testimonial Mitsubishi Reviews

Mitsubishi Outlander 2.0 DI-DC 138 bhp Diesel

Posted on 25th April 2018, 14:06

This is my second remap from Celtic Tuning and I'm never let down!

Its made my Outlander feel lighter and much more driveable, and now it pulls like a train too!

Can't recommend enough, even the guy how came out to perform the remap was professional and answered my many questions I had.

Very Happy! Looking forward to remap number 3!

Stage 1 remap carried out, wow what a difference...achieved 186.1bhp, pulls hard in every gear...6th now feels like 3rd ! Great personal service received, thank you!

See you guys at your new premises with our Audi.

Booked in for my first remap and the service was great, Luke explained everything I needed to know and Cam arrived when they said, even put up with all my questions. Slight problem came when it turned out my Lancer had been mapped before, badly.

Cam explained everything and put a new map in, left me to decide on the outcome and it's awesome, couldn't be happier!
