hey guys... well i got the external wastegate hooked up off my manifold along with the evoIII turbo... when i run boost off the wastegate and disconnect the boost controller... it holds at 12psi until redline (running boost off the spring...) its a tial 38mm wastegate.... when i hook up the vacuum lines to the boost controller the boost is no longer controlled... hitting 26+ psi... i was wondering what type of manual boost controller you guys use, and recommend.... thanks:dsm:

Are you sure you have your controller adjusted right? sounds like the problem to me, turn the nob all the way out and see if it still rises the high.


... dont turn it out so far that it will fall out later.


If you want to replace it then I would recomend a hallman MBC but just about any one that you can find from a shop like Buschur, SBR, ExtremePSi etc. should do

Reverse the hoses in and out of the EBC and try again.

Okay, where ever you vaccum source is(Bov line or side of turbo) That goes into the side of the WG. T into that line and into the boost solenoid NC side. COM side of the solenoid goes to the top of the WG. Set the boost a little above the WG spring, like 14-15 psi to confirm that your solenoid is working properly. If you get boost spike real bad, turn the gain down. If the boost falls off at high rpm's or keeps increasing as rpm's increase, raise the gain. Hope that helps, if you have any Q's my AIM name is the same as my user name on here.

It's pretty obvious that either you have a defective EBC or it's not hooked up right, what more do you want from us? :p

If you have a friend with a turboed car, maybe try it on their car..in the meantime, get yourself a Joe P MBC.

Take the Profec B back for a refund..if you can't, sell it on Ebay. Just clearly put 'I could not get this to work, so I am not sure if it actually works or not. Sold as is'. There's always somebody out there who'll buy it thinking they could probably get it to work. At least then you'll get SOME money out of it.

I'm guessing this is brand new? So why can't you just take it back to where you got it from for a refund?

Joe P and Hallman are two (in my opinion) of the best MBCs. I see cars with 3-4yr. old Hallman MBCs that are still tip-top. No corrosion, clogging or spring 'relaxing'.
