In our customers' words

We have not edited these down to one line. If you would rather speak to someone who has used us, ask and we will put you in touch.

They logged it, went away, came back and changed the file until it was right. That is the bit other places skip.
MMark T.BMW 330d, Stage 1
Booked in on the Saturday, done in a couple of hours. The car pulls from about two thousand revs now where before you had to work it. Same fuel use on my run to work, just a nicer drive.
DDaniel R.Golf GTI, Stage 1
Van is loaded most days and it used to drop out of top gear on every hill. It holds gear now and I am getting a few more miles out of a tank. Straightforward to deal with, no hard sell.
PPriya S.Transit Custom
Third car I have had mapped here. They logged it, went away, came back and changed the file until it was right. That is the bit other places skip.
MMark T.BMW 330d
Had a warning light nobody else could pin down. They found a split pipe in twenty minutes and did not charge me the earth for it. Went back for the map a month later.
CChloe A.Audi A3 TDI
Tows a twin axle caravan every other weekend. Completely different truck now, it sits at seventy without hunting for gears.
SStephen W.Ford Ranger
Upgraded intake and exhaust and they built the file around it rather than loading something off the shelf. Smooth all the way to the limiter.
AAmir K.Seat Leon Cupra
First time I had ever had anything like this done and they explained it without talking down to me. Car feels newer than it is.
RRachel M.Vauxhall Astra
Two vans done, both back on the road the same day. Sorted the paperwork for the fleet without me having to chase.

Leaving a review

If we got it right, tell someone

Almost everyone who comes to us was sent by somebody else, so a review genuinely matters to a workshop this size. If something was not right, ring us before you write it and give us the chance to sort it out.
