Look at my post about boost leaks here https://www.rx7club.com/forum/showth...ight=boost+leak

 

Since the link doesn't work, here is the procedure:
More than likely you have a boost leak somewhere. I've found that the best way to find boost leaks is to take some soda cans or tennis ***** or anything of the like, and put them in the intake hoses(from the airbox to the turbos). Clamp the hoses tightly around the cans. Next, get a blower nozzle for an air compressor that can have a vacuum hose slip on. Put the vacuum hose on the blower nozzle at one end and an intake nipple at the other end. Tighten the vacuum hose down with hose clamps at both ends. Turn the car on(not the engine though). Now lightly blow air into the intake with the blower. The air will have no where to go except where the leak is.
