MSP boost controller and gauges
 

If any Mazdaspeed owners have installed a boost controller, could you let me know which one you used, how difficult it was to install, and how well does it work? I'd just like to get some input so I can crank up the boost on this thing.

BE CAREFUL, mine was boosted up and when I took it back to stock for warranty work, they did a dionostic on my car and they are able to pull any boost spikes and readings from the computer. If you want e mail me and I will help you. I don't want to post it on the forum. zzooomm@msn.com
