I just installed my performance ECU tune from Eurocharged. This may sound like a dumb question but there is a reason for the question. How do I know if the tune actually installed? I followed the installation script word by word.
Reason for question: I installed a 65mm pulley but drove the car lightly until I installed the performance tune. There is definitely more power but how do I know if the additional power is the combination of the pulley and tune, or just the pulley?
Any feedback would be greatly appreciated.
Thanks
