Electronic Boost Controller Comparison - Product Test
We Hit The Dyno With Six Sophisticated Electronic Controllers And One Cheap Ball Valve

In all honesty, it kind of looks like a plumber got his hands on your car, but it sure does work. Turning the black-oxide coated bolt down against the spring makes adjustments. We gained around 1.5 psi of boost per turn. Two springs come with the kit; one is good for about 20 psi, the other even more. We never had a chance to try the other.
DSS has an improved design going into production that should eliminate much of the boost spiking experienced in this unit.
It'll also look much better, is manufactured from billet aluminum and be available in a number of anodized colors.
| CONTROLLER: JBC/DSS MBC |
| PRO | Works pretty darn good. |
| CON | Some boost spiking. Can't adjust inside the car. |
| COST | $65. You can get six of these for the next closest competitor. |
