If you want to get rid of the surge at 55kms then yes it was worth it, though it does still have some minor ones. I would say I am 90% happy with the ECU flash, power gain was noticeable and unlike using the power commander my fuel consumption has stayed around 250 for a tank full but that is only a guesstimate! though I still have the power commander hooked up but not actively working.....
