Customer Comments

Phil Anniss

Terry has done a great job with my T4. Running much smoother and 30% more power. Worth every penny and no better place to go. TH Performance are the best a for a good reason. Couldn’t be more pleased with the work. Thanks.

Tony Bryon

Absolutely over the moon with the service and what they’ve done to my van. The detox and remap are awesome.
Worth every penny it’s like a new van. Thank you😊

Jason Rate

Brilliant service as always. This time I had the cam-belt and water-pump changed, but whatever needs doing to my T5 it goes to Terry at TH Performance. He and his team know transporters inside out and backwards!
