Talk to Kurt (Mr Haney) here on the board. He will fix you up and this guy KNOWS what he's talking about. Had him flash the ECM on my '05 MXS C15 475. Before the flash, climbing Watino hill 8% for 2km loaded i dropped 4 1/2 gears and pulled the hill at about 30kph. Now, I drop 2 gears and pull the hill at 65-70 kph and my pyro NEVER goes over 850. You will never regret having Mr Haney flash your ECM.
