Testimonial Volkswagen Reviews

Volkswagen CC 2.0 TDI 174 bhp

Got my CC remapped the day I bought it! The added mid-range power is excellent. Celtic Tuning quote 228hp, but I've yet to test it out on a Dyno so unsure of the exact number.

What I did test however, was the 0-60 times. Standard the car is 8.2s to 60 (8.4 to 62) and I got the car to 60 in 6.2 & 6.5s on the two runs I've done so far (in the wet!!).

To say I'm happy is an understatement. Top job!

Great service overall and an excellent technician (Kevin), he really was very good at his job and if you're lucky enough to get him, rest assured you won't be disappointed.

The Lupo has been transformed, the biggest difference being throttle response you don't get a massive bhp increase obviously but coupled to other mods the remap is the icing on the cake.

VW Caddy Maxi 2.0 140 to 197bhp

Came over from Germany for a remap, EGR delete and Vmax delete Very impressed.

The car runs smoother, pick up is cleaner and it's still returning great mpg. I have done 3000km in the 7 days and it absolutely hauls on the autobahn now. Importantly, the back of the car is clean, so no over fuelling or excessive smoke.

This is VW's emissions scandal engine running as it should. Many thanks. Rick Harrison, Black Forest, Germany
