J-Spec Boost Controller

Boost controllers dont turn boost down - they can only raise boost.

 

If your on stock j-spec tubbies, decatted with restrictor ring and you can reach 1.2 bar on WOT then there isnt much point in getting a boost controller.

 

mmmm you can have high or low setting, well you can on mine;)

A decent boost controller allows you set gain, which helps the turbos spool up quicker.

 

Personally I would have a restrictor ring to limit boost to around 1bar, then use the boost controller to raise boost to 1.2bar. This also allows control over boost levels when the colder whether comes and the boost naturally rises a little due to the cooler/denser air.

Sorry Gaz, I misunderstood your first post.

 

I thought you were saying a boost controller can reduce boost lower than its stock amount - ie: if your getting 1bar boost without a boost controller, you can install one and set boost to 0.8.
