Noticed my 87 Daytona Turbo 1 log intake, has a mp performance computer unsure of calibration, but usually maxed out at 12 psi. Lately it pegs the factory boost gauge at 15-16 and sets code 45. Thinking it is the boost control solenoid. Any idea where to find one? don't see them on rock auto or fwd performance.

Am I going down the right path? Also have an 88 T-11 parts car, can I use one from it?
