SCT Tuner

The maps should almost be identical between the two cars, no? I dont see why they cant offer support for the MS6 as well.

true if you want the canned tunes, but SCT tunes that are tuned from SCT dealers ie: like Innovative Diesel work best. The dealer will need your computer code listed in most cases on the ecm and will also need the strategy code that will require the SCT Xcalibrator 2 to pull the code. One of the advantages is that you can have your dealer custom tune to your needs like if you add the bottle . So, if SCT ever comes out with a programer for the speed3 there may be up to 10 less or more strategy codes for the speed3 & speed6
