Any pro MPI supporters out there. .
Oh Ya, there are plenty of us around.
I am deeply in the MPI camp, and the reason is that MPI is a major participant in our forums. Matt is online every single day always dropping in and participating in our threads. That means Tech Support is always available, and for "me" that is of utmost importance.
MCExpress makes a great product. No doubt about it.
You will find LOADS of users with their product.
I also think that MPI makes a pretty solid product as well, probably has something to do with Yamaha choosing them as their OEM supplier for both Turbo and Superchargers on their sleds...
If you are doing the install of the kit yourself, then MPI's presence here might make that install just a bit more friendly. If you are having your shop do it, then I would probably go with the one your shop techs are more familiar and comfortable with..
