After testing several boost controllers available on the market, we came to the conclusion that the best solution for manual adjustment of boost pressure is the ball and spring type controller. The Dual Ball and Spring design was perfected by Joe Pampena, of DSM fame, and that is the basis for this controller. Ours is a variation on the Pampena design tailored to Toyota Turbo applications, specifically the MR2 turbo.

We have been working with Joe to make his controller more of a 'plug and play' unit for the MR2 - this is the result.
