boost controller Question
ok whell i just bought a Profec type S and was wondering about the gain *** i mean yes i am a noob at the boost controller thing since i never had one but i would like to know how to work it.. i know it does something with the waste gate.. i would like to know basically where it should be normal driving and where it should be at rough driving... FYI i have stock twins still

The waste gate lets exhaust pressure bypass the turbine when boost gets too high.
A boost controller makes that happen at a higher pressure.
The gain **** sets how high.

I am curious about this too... So if its not set properly it could hurt your turbo? I have never fiddled with mine. If you adjust it does the boost come on differently? Does it mess up how the car is tuned

^ Same boat. I have a MBC and i'm not sure if i'm operating it right. This is what I think (please correct me if i'm wrong).
Turn counter-clockwise (tighten) = less boost
Turn clockwise (loosen) = more boost
Not sure how it works in the EBC.

the MBC set up depends on wether you have a extrenal W/G or internal... best thing for you to do is get in touch with the MFR and have them fax you a copy of the manual...
as for the EBC... it will do two things... It sets the boost level and it also keeps the W/G closed longer to induce faster spool...
Lets say you have a 7 lbs spring in your wastegate... as boost is created the wastegate opens slowly... so at say 1psi the wastegate starts to open, 2-3 psi it's a little more open... and full open by 7psi
put a EBC in and set it to 7lbs, the max boost will still be 7lbs but the EBC will keep the W/G closed until 5-6 psi and be fully open by 7psi therefore it doesnt "waste" valuable exhaust gasses while creating boost
hope that makes sense
the gain set how quickly it starts to open... this is tuned to the turbo characteristics
