I have a MM3 with tuning from DRD, I typically run the 30hp tune exclusively because I tow my 10k trailer twice a month.

I want to try the 120hp tune for daily driving but I spent 90% of my time on the interstate going 75mph+ for hundreds of miles at a time. A proper transmission relearn is almost impossible because the highway is 1 mile from my house.

what’s the real deal with switching power levels? Can I simply switch and drive normally? Or is that not advisable?
