manual boost controller question

[Sean Donn]

this very well may be a ridiculous question but how do you know exactly what boost your turning your ball and spring knob to without having to run it and watch the boost gauge? I have tunerpro rt hooked up while adjusting my boost, however from what i've messed with I can't figure out anything that tells me what boost i'm at.

also one last thing, i've noticed that when turning the bolt and compressing the spring to add boost it takes a lot of rotation to increase boost a small amount is that normal? my bolt only shows about 2 screw treads left after clockwise turning and when doing a WOT run It still only boosts to about 20 psi. is that normal? by the way if any of my reasoning or actions in this comment are retarded I take full responsibility and humiliation.

Waht MBC are you using?

You probably need a stiffer wastegate actuator spring. Make sure you are watching for knock/detonation.

sadly i'm unsure but it looks identical to this

I am wondering if this has anything to do with my lame quarter mile times(fastest of14.3) today at the track. I was running tunerpro rt all day and never had any unusual graphs or anthing, no knock retard, only a code 35 IAC error. from what I could see my boost gauge never passed about 16 for any of the runs

Re: manual boost controller question

you would need a stiffer spring in the valve for more boost, and adjust your wastegate rod also if your having flucuating boost readings.
