Is the part no for both of these the same? Ive read on here that the Vic and vtc are interchangeable, is the PRC also?

yes they are interchangeable. the egr, prc, vics, and vtcs all use the same solenoid. hope it fixes your issue! i found mine a little cheaper for $10 a pop on ebay if you need to save some money.

I still plan on taking them off and inspecting them. My boost gauge was acting funny as well and it is tapped between the vtc and Vic, perhaps a restriction?

Driving home, I see the boost gauge is off alittle and slow to act. I know im building boost, the guage is just not reading right.

Does the flow go through the vtc then the Vic or vice versa?
This would explain my guage acting funny since the code came up

Another observation, my boost gauge won't show boost till one of those open up. It will start showing boost at around 4k, then it quickly shows the 6.5-7lbs(stock 4 me). My code was for the VIC and PRC. Doesn't the VTC open up at some RPM?
