I just got off the "Tech Line" with Ford Racing and had an interesting discussion regarding this. It was immediately pointed out to me (as I previously hinted at) that there is likely zero issue with the spring changes (rate increases are pretty mild) and to look at the GT350 and the fact that FP had no issue with their spring kit and mag/non-mag dampers. I purchased these very springs for my own GT350 when I had it.
2015-2018 MUSTANG GT350 LOWERING SPRINGS
I didn't get far with mention of reflashing when I mentioned that I see they also sell Mag ride handling packs that include a Procal tool with a calibration file to be uploaded to the VDM. I find it interesting that a calibration file was necessary here. Seems the engineer that developed the kit, Andy Vrenko, has moved on from FP.
FORD PERFORMANCE MUSTANG MAGNERIDE HANDLING PACK
I can get through to some other engineers there as well as talking to some at DSC Sport. We'll figure it out.
