I'm working on a customer car, relatively stock 94 RX-7 automatic, and having problems with boost. Hits 7psi in 1st and 2nd, sometimes, by redline and only 3psi dropping to 0psi in third gear with "hold" button activated. Only makes 3psi dropping to 0psi in normal shift mode in all gears. I replaced turbos and transmission because they were damaged before I noticed this boost situation, not because of this problem. Any ideas?
