Any other thoughts ?

It sounds like you having a similar issue as a friend of mine. It ended up partly being that the MBC which was also the Hallman. she was just boosting 15 lbs after the install.

and I found te replacement srpings for the Hallman. it looks like you have the Heavy spring.

Word-


I'm waiting to hear back from Emery today and see what he has to say.

I just installed mine over the weekend. Mine came with 2 springs and the ceramic ball. I think if you just get the Pro, and not the Pro RX, it just comes with a steel ball and the light spring, or at least that is impression I got from reading the different product descriptions on the site. I think the light spring is only strong enough for about 15-16PSI. I have the heavy spring installed, and I used the BOV line to wastegate method, and I'm boosting about 20PSI perfectly fine. I still have plenty of clockwise turns left on the MBC for when I get my tune too

 

Thanks for the reply man


It definitely seems the spring is what was causing the issue.

I wish I didn't send my MBC back to STM to have them check it out. Oh well, live and learn.

Hopefully I'll have it back for Wednesday so I can still hit the strip!

One other thing I'd like to add, is anyone else impressed with how well this MBC holds a consistent boost to redline? I know its mainly the turbo's job to do this, but with the stock boost setup, it would taper down about 3PSI at redline. The Hallman holds 20 from beginning to end. Can I expect the same when I get my tune and raise the boost even more?

 

Mine tapers from 23 psi to 21 psi.

Do you have the evo8 or 9 turbo on yours? I heard the 9 holds boost better to redline, correct me if I'm wrong. I'm still new to this platform.

 

Everything looked fine, But I changed the ball and spring out anyhow. Its on its way back to you now.

Thanks

Awesome, Thanks Emery!

Hopefully I'll be able to turn up boost this time

So, binky are you not driving your car until you get your MBC back, huh buddy? Or did uou put it back to stock BCS for the time being?

 

Nope....not driving it It's been a while since I went for a rip....it Sucks


I had an Apexi AVC-R boost controller in there, I took it all out before I installed this one. I have the stock boost control solenoid still hooked up, so it doesn't throw a CEL, but naw, I wasn't planning on hooking it back up.


Bummer huh?

thanks for the find! I needed the heavy spring since mine got out of wack from overtightening.
