Porsche Boxster 986 3.2s

I am over the moon with these guys....Lots more Torque and Hp....Goes like a dream. So confident now. They are the best in the business....I can't praise them enough. They will give you the best advise ever.... And do the best job that you've ever had. If you go in with all guns blazing, thinking that you know better, they will shoot you down. Listen to them carefully because they are old school and new school. They've heard it all before....and definitely know it all. Thank you very very much Eric and Elliot, for your honesty, and hard work... and also for putting me straight.

Porsche 986s

This was my last chance saloon. I was sick to death of being robbed by cowboy mechanics, who never did the job properly. I went on the web, read everything About TURNER DIAGNOSTICS. Gave them a ring.. took my car on an hour's drive to see them. Was met by Elliott. I explained while he patiently listened to my story. He said that he'd heard it all before. I left my car with them. 2 days later I got a call to say it was all done and what was done. This made me very happy and I eagerly stopped everything I was doing and jumped on a train from Camden Town. I couldn't stop thinking about what it was going to be like to drive. When I got there I saw the car outside waiting for me. I called out and Elliot came out with a lovely smile on his face. I knew this was the Guy I'd been looking for. He told me to take it for a spin up the hill, opposite. I did, and it was magnificent. I got back and Eric came out while Elliott ran me through it all. I cannot thank them enough for what they have done. The drive home was magical, and the drive today and everyday is the same. Hats off to TURNER DIAGNOSTICS. Father and Son.

TR6 PI tune up

Just wanted to say a huge thank you to Elliot and Eric for the great work they did with my TR6 PI. The car runs smoother now with good throttle response. Will hopefully see better fuel economy as she was running very rich. Both are friendly and knowledgeable and I have no problem in recommending them to others.

P38

Dear Elliot, I am so appreciative of your complete transformation of my P38. The 500 miles round trip from my U.K. home was inconsequential when receiving such knowledge and attention to detail. My anxieties of the numerous systems were alleviated within minutes of becoming acquainted with you. The return journey from your premises to Co Durham exceeded all expectations of how a P38 can actually perform, if maintained by a high caliber diagnostic center such as Turners. On time, on budget and a pleasure to deal with! Yours sincerely, Stephen Tomlinson.

Turner Diagnostics transformed my Range Rover P38 exactly the way I had wanted and some...

My Range Rover P38 4.6 (Thor engine) had a known flat spot of factory origin, really noticeable when pulling away from roundabouts/junctions and especially without having stopped fully. My commute of 34 miles each way includes fourteen roundabouts (I go right across Milton Keynes) so this was a real frustration for me... I talked this through with the Elliott at Turner Diagnostics, and they came up with exactly what I asked for, which was re-mapping that took all that flatness away - none of this higher revs and extra power stuff which I did not need. My P38 is now a different and much more gratifying drive - I am delighted!! As a bonus, I can also attest that I have reclaimed around 10% on the MPGs as well... that's more than Elliott and co. had suggested would be the case after the re-map! To anyone with a P38 in particular I highly recommend the remap by Turner Diagnostics... I should have had the work done a lot sooner, and I liked the fact that there was no over-selling from them... it was sorted in a day, was a pleasure all round and still is!

I wanted to say thanks for the work on my P38 RR

I wanted to say thanks for the work on my P38 RR. You sorted out a number of problems and spotted a couple more issues that needed fixing - The car drives and handles so much better now and labour charges were more than fair. Also appreciate Elliott's help when called with honest, straightforward advice on some work I was doing to the car myself. Definitely worth the 90 odd mile round trip to visit you and will definitely be back if I need more work doing. Thanks again, Scott
