works like a charm! easily adjusted and set up, do yourself a favor and buy a boost gauge and some more tubing if you want to be able to dial it in while driving if you cannot go to the dyno to tune it.

Did the function, easy to install and bumped factory pressure 7 psi to 13 psi . Going to install longer duration cams and adjust psi to 17+ psi. Make sure that you place the air lines in the right flow direction , saw u-tube guys putting lines in wrong flow pattern.
Doesn't seem to work well

Product looks nice, however didn't function correctly. With preinstalled spring, if I was fully to the "-" I would see stock boost 7.5psi, any miniscule adjustment towards "+" and I would be 14+psi and hitting fuel cut. Swapped out for the smaller spring and same behavior.
I think something is wrong with it.
It seems to be nice material quality, but doesn't function well.
I put my buddy's turbo xs mbc on the car, plumbed into the same vacuum fittings and that works fine.

Don't bother

Bought this as a quick way to determine a problem. Install was simple, but it doesn't let me go over 10lb of boost. Also, it's already jammed up, meaning I can't turn the knob to add/reduce boost.
Works as [email protected], stock fuel system

Works as intended for a 91' 1st gen 3000gt VR4. Do not install without a boost gauge already in place.
