Good morning ladies and gents. I have a 2018 bmw m4 comp pack and was wondering to hear your input. BMS sells a kit for 1,899 claiming to achieve 600hp is this a better route to take if i still want to keep my warranty? obviously i would remove all upgraded parts and put oem ones back on before taking to dealer. i was told by my service advisor at my dealership that they can still track BM3 even if you reset it back to stock settings... i like the fact that Bm3 removes speed limiter. has any one had warranty work and reverted thier cars back to stock with BM3? any input will help! thanks. i pasted the link for the jb4 600hp package.
