Boost Controller Question
 

If a boost controller is installed how low can you set the boost? I am not quite sure how they work. For example if there is bad weather can i turn the boost off or really low? thanks!

you can not set it any lower then what you are running without one.

boost controllers only raise boost.

lol, ok thanks man. Is there any product that you can use to diable the turbos when not wanted?

Actually
 

i think i did lower it a bit with my Knightsport EBS2 on my S5, when turned down maximum i only boost 7,8 psi, but then again that is around stock i guess... i have upgraded T04B Hybrid with very ported stock wastegate, and i think the porting is the answer.... i was avtually surpised i could boost that low, i thought that with all my mods it would be higher, since i have both Race-cat and downpipe (see modlist)

It's the pedal on the right. ;)
