Its actually getting a power commander V in a few weeks at C&M Motorcycles, but i need to sort this problem out first. Tuning it may fix it but theres definately a problem. Dont want to tune it then later down the track the tune goes out of wack lol.

Your photo looks like a 2005 model ???
So do you need a power commander? It was my understanding you could flash the original ECU for the same results. What's the benefits of a power commander?
