But my car already boosts 15psi....whats the difference?Exhaust Depot said:EBC = Electronic boost controller
MBC + Manual boost controller.
The electonic one you can use to controll your boost in the car and it also have various features like overboost protection etc.
A manual one allows you to raise the boost manual. IN other words, you have to set it then drive your car to see if your boosting enoug of to much.
15psi is a safe number to boost on our car.
