Problem is I find the dealers are not setup to properly complete a supercharger upgrade. Missing the dyno and experience in tuning. I actually had all my work done with a speed shop who used Davenport for a remote tune. The dealer I'm at I think is probably rare in that they still honor the warranty but a lot has to do with the fact the head mechanic is very comfortable with the upgrades I did because he himself works on mods outside of work. As I mentioned I think that doing upgrades comes with risk and one would be losing the warranty for sure. So much stuff can go wrong just in the tune so you need to make sure you pick the right place and there is a reason why they get you to sign the waiver before they put the car on the dyno lol.
