Damnitt, the car has gotten worse again, with the new AFM it ran good for 5 days and has now gone to running spluttery,bogging down after about 30 mins of driving or so??!.


The car has ECUTEK on the ECU, can any tuner alter settings on this or can only licenced ECUTEK Tuners alter the tune?.Is it possible for a car to lose its tune even though nothing has been modified since the tune was done?.....
