I usually run 20 pounds of boost out of the 14b on the 92 Talon with no problems. I just changed out the timing belt and water pump and stiffened up the motor mounts and took it out and it will now only build up 10 pounds of boost. I have a manual boost controler and I have adjusted it but still can only build up 10 pounds. I have checked for exhaust leaks but none are to be found. All my timing marks are to spec. Any ideas?
