Haydn ,Renault Modus Van 1.5 DCI

Excellent Fast Service. I found your employees very helpful even with after service, and also keen to answer any questions i had. Has given my car a well needed power increase and fuel economy is great.

Mike,Isuzu Rodeo 3.0L

Very impressed. Noticeably improved acceleration and responsiveness as well as slightly better economy. Towing now much easier with heavy loads as well as being more fun to drive without. Well worth the money and much better value than paying manufacturer for same engine with higher power output.
