A 100% professional service by a company that cares.

Rare to find someone like Keith who gave me all the advice I needed to make my own decisions.

Really pleased with the result of the remapping of my vehicle. The car performs better with the power and efficiency plain to see.

Thank you Keith, you are a class act.

Friendly & professional diesel experts. After having previous excellent work done by Keith I wouldn't have trusted any other company with remapping my Mercedes E320 CDI.

Told by my garage injector had gone on my mk5 tdi golf. Got them all out and United diesel checked them over to find they were fine. Speaking to Keith he mentioned to check the wiring harness at the back of the injectors common fault and he was right !!. Car runs sweet.Very highly recommended .

I had my vivaro sportive van remapped in September 2014, I am very pleased with the results , the van now is more responsive and pulls a lot better through higher revs now. I noticed a sight increase in fuel economy and also use their fuel additive .

The service I received was excellent very friendly and gave plenty of advice ,also lent his van whilst I was waiting which I appreciated. full marks would definitely recommend .Thank you.

Fantastic service! I have a seat ibiza tdi, smoking under heavy load. Travelled up from Salisbury, and in no time kieth and his son had the cam cover off and the suspect injector out and tested. The car being highly tuned also had a remap and after a few test runs the car was running great! A great family run business, kieth and his son don't mind getting there hands dirty! And a lovely cuppa from his wife as I waited. Great hospitality and attention to detail. I wouldn't hesitate to return to them again.

Just had my BMW 118d remapped, it now pulls much better and also is now slightly better on fuel economy. Keith was most helpful and explained everything that was going to happen. Very highly reconmended.

I have recently had my Audi A4 avant 1.8 diesel mapped and have noticed a massive difference straight away. The car pulls better, has much more torque and feels much smoother on idle and drive. The mpg is looking better already as well. Thanks again and will be recommending you to everyone!

Where no one else could help improve the performance of our Fiat based Hymer motorhome we were advised to speak to Keith. Our 2.8idTD engine had no ECU which meant no possibility of having a remap, so 9 out of 10 companies turned us away. No problem for Keith though, he built us a bespoke set of injectors & once fitted the transformation of our Hymer was fantastic & I now enjoy driving it!
