Replaced the oversized t-bolt clamps & some worm-drive clamps with spiffy constant-torque clamps (intercooler piping). Back to 15psi from 7psi- she's fast again! 
I picked up a used Berk exhaust also..just waiting for the guy to send the hardware (apparently he forgot to ship the bolts and gaskets) and we'll get that installed as well.
