I used to get an easy 23+ psi of boost but have only been getting around 15 psi for a while now. Engine runs great and readily hits 15-16 psi max. Think I have a leak?

Could be, check you IC tubing clamps elbows and tubes .
Any CEL codes?

...and check those intercooler tubes CAREFULLY!! I didn't spot a crack in my cool-side pipe and spent a month chasing my own tail...

Hey Rlee63a4, just curious if you identified any boost leaks... or codes... does your "power gauge" on the RPD (if yours is so-equipped) show the same hp/torque that it had been?

Sorry, JSK. I haven't had time to perform any checks. Car still running good. So, those checks will have to wait until I get a mountain of family, house, other car stuff done first. Car is not equipped with an RPD. More to come...in time.
