James replaced the Timing Chains on my Jaguar XF 2.0d which had the infamous timing chain rattle. From diagnosis to repair, there was great communication throughout. I was sent pictures and even a video of the work carried out and the Jag now runs better than ever!

Just finished our trouble free summer touring in our 81 T25. Only made possible thanks to the brilliance of James and Kerrie at JS. If there’s anyone better with tuning the aircooled engine, I’ve yet to meet them.

Fantastic service, helped me out with an ongoing issue. Carried out a stage 1 remap while there. The car now drives like a dream. Would highly recommend JSA, most genuine bloke I’ve met, thanks again.

Delighted to have found James who has a specialist knowledge of Aircooled VW’s. My Karmann Ghia is now oil leak free and running beautifully, after years of struggling to get the sump oil leaks sorted. Highly recommended.
