Commander not reading high boost ???

Ever since I put my TST on the commander will only read 23 psi. max. I've been using the remote on the TST for boost. I've got it set to back off at 34 psi and I can get to that in a heartbeat on the right setting. On acceleration both the Commander and TST boost reading will climb almost identically but the Commander stops at 23 and the TST keeps going. Any Ideas?

You need to move the blue wire on the Commander to the TST harness where it goes into the actual sensor.
