I changed it about 5000 miles ago. I bought a new one for a spare but installed it and kept the old one for the spare. I didn't notice any difference in the way it ran. .... Thanks

When I changed from the stock filter to the 6637 the intake was clean. I made sure my clamps were secure and sealed the joints with a Polyurethane sealant for insurance. There's only a few thousand miles on the filter..
I checked for leaks everywhere you guys directed and didn't find any.

There's a slot on the arm of the EBPV that is just visible from the top and returns to that place, toward the passenger side, when moved so I'm thinking it's full open but it's hard to move and I'm wondering if it is really full open. Maybe hitting something as mentioned earlier.. By hard I mean with a bar. It doesn't seem right but being the importance of it staying open maybe that's the way it should be?
I can't find a meaning of the PO236 code the programmer shows.

Thanks again...

po236 is for boost below 13 psi. i have code and 11 psi. replaced upipes and manifolds-no difference! the thing that gets me is when i turn my ts chip up my boost goes up to 17 psi!!! i believe the only thing the chip changes is injection timing and pressure. what does that tell you? is it icp pressure causing low boost on stock mode? hpop, etc. i need a guru's help please.

Do you still have you CAT converter??? That may be plugged causing high restriction driving up EGT's and dropping your boost pressures.

2nd, wow to old thread, good to see the search button is being used. I know I'm bad for the lack of.
