It's a piggy back chip that goes in before the ECU and modifies the input signals. This way when you go in for service it can be taken out in 3 minutes. Like it was never there. Its made by TDI Tuning over in the UK. So far I am very happy with the performance of the vehicle and if you can keep your foot out of the throttle there is improvement in gas mileage.Hi mate,
Would you please provide the details of the guys who did the tune on your Kona and provide a ballpark costing if possible. Not sure when Covid will permit me to drive down but it'd be good to know.
I've never had a tune done. How long does it take? Is it an iterative process where they tweek the tune periodically or is it a set and forget.
Appreciate your response. Thanx
