I thought I posted these here before, to fix my stumble between 2400- 3000rpm I "T" the line off #4 intake manifold runner into the hose off the blow off valve. That hose sends a signal to the fuel pressure regulator.

 

Reset the ecu and drive the car.

@Max Capacity Do you have a parts list of what you used for this?  Looks like a brass plumbing T (1/4"?) and some zip ties?  Does anything need to be done where the old runner connection is?  Would it be a little easier to use worm clamps instead of zip ties (for needing to remove the intercooler in the future)?

Yes, a brass T from the local hardware store. You can find barb style T's if you look around. https://www.google.com/search?q=brass+barb+style+t+fitting&rlz=1C1OKWM_enUS906US906&oq=brass+barb+style+T+&aqs=chrome.1.69i57j33i160l2j33i299j33i22i29i30l2j33i15i22i29i30l2j33i22i29i30.12414j0j15&sourceid=chrome&ie=UTF-8

Yes screw type clamps will work. Notice on my wagon, Aluminum color tmic, there's no zip tie there at BOV. That car dynoed at 21psi.

Nothing needs to be done to the car's nipples.
