Absolutely excellent results. The increase in low rev torque is amazing, The car now pulls like a steam train, great for towing. Fuel economy is actually better unless you boot it all the time. I am averaging 47mpg on a 14 mile commuter run including country A road and town traffic queues. Easily 50+ on a longer run if I stay below 80mph.

Thoroughly recommended

Took my Berlingo van to Celtic Tuning HQ today for a stage 2 remap, what a difference it has made.

I had a 180 mile trip back home so had plenty of time to feel what an improvement it has made, going from 75bhp up to 120+bhp, it pulls all the way through the rev range, once in top gear it stays there no need to drop down a cog. A big improvement in economy also 180miles @ 60/70 mph 49.5 mpg avg before map, 180miles @60/70mph 60.1mpg avg after map !

Polite staff, nice premises, great price. Brilliant.

Having had Celtic Tuning map most if not all of my previous cars, I was expecting more of the same. And straight away the team did not disappoint.

My DS5 is more responsive, uses all the rev range and deliveries a more excitable driving experience. The engine pulls well, strong and shifts via the paddles smooth and efficiently.

Thank you to the team once again! Consider putting me down for a long term loyalty card ;)

I had an ECU remap couple weeks ago, what a difference. I am getting 10 more mpg and the van is so much nicer to drive. I have had this van from new my only regret is i didnt have it done sooner thanks for superb job.
