The 5 speed Allison is not capable of handling the same amount of power as the 6 speed. We do TCM tuning on the 5 speed with all our ECM tunes. The operating system on the 04.5-05 LLY is not a very good calibration to use, so we switch to a better calibration. An Autocal is not capable of switching the calibration, so you have to have a v2 cable to do that. There are many benefits to having a good tcm calibration, but if you have an Autocal you can't change the os.
