Easy to fit, easy to adjust & a very different car to drive. Smoother gear changes, pick-up instant, acceleration mid-range incredible. All this & better fuel economy. Thank you.

Received chip for Martins car and installed it in 5 minutes. Was extremely impressed with the improved power and torque. Martins son and myself both picked up new 2.0 tdi Golfs today so I imagine you will be getting an order for another 2 in the not to distant future. Thanks again very impressed with the chip and service you have provided.
