Last week I received JK's boost controller and plugged it in. I dialed it up one full turn and as of yet have not seen any side effects except one. While cruising on the freeway I was pulling about 4-5 PSI and all of a sudden the boost just dropped to 0. While pressing on the pedal but not unlocking the torque converter boost remained at 0. If I put it on the floor the would pop right up to about 8 then drop to 5 and would cruise again at 4-5. This has done this twice in the past week. Only while cruising on the freeway and both times I was able to see boost only after putting the pedal on the floor for a a couple of seconds. Any thoughts?

Wastegate solenoid is probably failing. Kennedy suggests shooting some WD-40 into them to free them up. You might try that.
