Good day my fellow VR4's
Having some issues controlling boost on my newly installed Hallman MBC...I know a few of you are spot on regarding using the 1g bcs with DSMLINK-I will soon.
Nonetheless, the issue is I get upwards to a 10 to 12 lb spike- 10 to 11 lbs at 3200 rpm to 21 to 23 lbs at 6500 rpm with the MBC being hooked up to the pre TB bung-on the TB elbow and the external wastegate.
If I try to hook it up to the bung on the compressor housing it hits like the devil himself, but I cannot get it to drop less then 24 lbs???
Any thoughts?
You guys rock and thank you!

Per some help from Vegas on Dsmtuners here is the issue with the bung on the turbo. Question why would it be like that with an external cap and second can I just put another open bung on the compressor and hook up the mbc from there as the boost source?

Yes
