I know everyone always wants more boost more power. i need the opposite. i cracked a rear seal on my S5 TII stock. still drivable crappy idle and actually pretty good power still. but i need to drive it untill i can get the money to rebuild it. Is there a way to reduce boost from the turbo. like unplugg or block something in the mean time.

Thanks

 

Don't go WOT.

You could also disconnect your wastegate actuator arm so it's bypassing all the time (flapping freely), you won't be able to build much boost that way.
