Product Description

1986-1987 Buick Turbo Regal -

Here is a clever product that will give you a little more instant boost.

Your original boost controller is very progressive. With this new RJC Boost Controller, it is no longer progressive, which means - if you have your boost level set at 15 psi, this lets your actuator stay shut until 15 psi, then it opens fully.

The end result is you have reduced turbo lag and it makes part throttle boost much more responsive and allows you to run a little bit larger turbo than you normally could with a stock torque converter. The car feels a lot more powerful.

The stock boost controller system is adequate for stock situations and boost levels. When you start to up boost levels to make more power, you may run into a problem. Once the wastegate actuator rod is shortened to achieve say 20 psi of boost, it will have very little travel left on the rod, so now when the load is high in third gear, the actuator can’t fully open and boost creeps up.

By letting this boost controller control the amount of boost that the wastegate actuator “sees", it will eliminate boost creep.
