JoeH Posted September 8, 2024 Share Posted September 8, 2024 Are there any parts differences? My 2003 MR688S is a bit of a dog. The 1480 ft lbs with 60% torque rise sounds nicer than I forget what the 350's torque with like 30% torque rise. Would be nice if all I have to do is get the dealer to reprogram the EECU. It's paired to an Allison HD4560, which according to the Allison sheet I looked up seems to be rated for 500hp/1680 ft lbs. Not sure if the spec sheet is for a newer generation 4500 series or if it covers mine.
