As title says really, what size should the restrictor pill be on a 1998 UK turbo with prodrive ecu in it? Also what pipe should it be in? Boosts at 1.1 bar most of the time but sometimes in 4th and 5th it overboosts.

Cheers for any help.

 

are you running a 3 port ?? if so i dont think you need a pill

 

No just standard 2 port?

 

when you say it overboosts, are you getting boost cut or just momentarily overboosts?

Cheers for that.

Yes hits boost cut in 5th everytime, sometimes 4th Fine all other gears.

Any ideas anyone?

 

boost cut is upround 1.35bar on PPP! id be inclined to unwind the actuator arm a half turn at a time until you get the desired level.

or a general way to manually set it so that its preloaded by 1/4 of the hole on the arm, that is you need to pull the acutuator arm to fit onto the stud.

 

Overboost sorted, found a wee split in the pipe from the boost solenoid
