I just did a log last night and notices that my boost spikes at ~3400 rpms at 17.83 psi and drops down to ~15 then tapers down to ~12 at 5600 rpms. I know the car falls flat on its face after a certain RPM, but isn't that at 5800 rpms?

Here is the attached Datalog:

So many views and no one has an opinion.

Are you still on stock tuning? If so, yeah that's perfectly normal.

Yeah I am on stock tuning. I know that on stock tuning boost dropped off after 5800 rpms, but to start tapering off at around 4k rpms seems a bit odd, even if I am still on a stock tune. Can anybody else chime in on this?

I have an adjustable BOV and want to know if I should just tighten it up a bit. I know I can just do it and see what happens, but I will not be able to do a log for a little while so I thought I might come to the forums for some enlightenment.

Anybody?

Perfectly normal for a car with just a MS CAI. That's how mine was.

Oh trust me, I get my fair share of knock. This run must have been a fluke, because I usually have knock. Sometimes as bad as 5. :shock: The other day I was driving with my girl and was accelerating and the car knocked and even she was like "wtf is that?". I still need to either upgrade my TIC or get a 2 1/4" t-bolt clamp to replace the clamp from TIC to turbo. The stocker is a POS and can never get tight. I am hoping that is why my car is knocking so much.
