What Our Clients Say

Testimonials

Skoda Fabia - Very pleased the outcome, car performs extremely well now. Would definitely recommend.

Callum - Essex

I recently took my BMW 120d to JJ TUNING for a Stage 1 remap, along with DPF and EGR solutions. During the initial vehicle health check, the team discovered a significant coolant leak originating from the temperature sensor. They promptly fixed the leak before proceeding with the tuning work I had scheduled. The attention to detail and thoroughness displayed by JJ TUNING were truly impressive. My car now performs better than ever, and I couldn’t be happier with the service provided. Highly recommended!

Jay - Chelmsford

I recently brought my BMW 118d to JJ TUNING due to a blocked DPF. The team provided exceptional service, addressing the DPF issue along with EGR solutions and a Stage 1 remap. These BMWs truly benefit from a remap, and I was thrilled with the impressive gains in performance. The expertise and professionalism at JJ TUNING exceeded my expectations, and my car now runs better than ever.

Carl - Witham

Took my Ford Transit to JJ TUNING for the removal of the speed limiter. The team did an excellent job, and I am no longer restricted to 68mph on the motorways. The entire process was smooth and professional.
