Unknown 06' Boost leak?

[wcjp]

Started on the way home tonite. As boost gauge climbs, what sounds like a boost leak from the dash/engine compartment starts. Boost line and gauge separately and together hold vacuum and 15lbs of pressure from compressor. I tightened all boost clamps(not loose anyways). Any ideas? Current mileage is about 19k. No changes or mods for 4k miles. At 15k miles, I modified stock airbox. At 4k miles injectors were modified.



Tried to pressurize engine tonite. Need to plug exhaust and intake this weekend. Truck will sit tomorrow. Gauge is dual Westach.

check the intake side ic tube, as it is plastic.

As of 05. 5 IC are all aluminum, no plastic end tanks. Got mine replaced under warranty for a blown out end tank.

I was not talking about the end tanks. The tube between the IC and the intake horn are plastic.

Never trouble shoot at night after work when tired. Problem was the boost line to gauge. I did find an empty Coleman propane tank makes a great plug for the air intake. I also found the 06' has a draft tube. Didn't think the CR's had a dump tube.
