A buddy of mine has an 09 monster 1100s. He bought some V&H cans for it and was looking at an DP full system ECU online. I know that the tune installed on them is obviously different than stock. My question is are they worth the money? Is there anything about the stock ECU that would limit it just being reflashed for the same effect as the DP ECU. I see them on ebay from time to time and wonder why people spend the money on them if its possible to get the same effect with what you already have. Any input would be appreciated.
