what manual boost controller
I've heard a good one is the Hallman MBC but I do not have one yet. The diff between elec. and MBC is mainly the convenience of not having to pop the hood to change settings. On an elec., you can store settings and change them with the click of a button.
Try http://www.boostcontroller.com you can also find them on E bay, I have one almost brand new if you want it, came with a parts car, PM if interested, it was about to go on E bay
