Fitting a mechanical boost controller.

[doski]

yea the cheep controllers are seen as bleed valves and can be very prone to spiking in the boost and i ran one of the apex performance manual ones for i while and they come highly recomended. I would agree with you 30psi as to ditch off the t-piece. Every manual one i have seen only has 2 ports... in and out which you just put inline on the pipe that goes on to the actuator

Best get it apart, if its a bleed valve then you will need the t piece, if its a ball and spring job it won't
