Ive lost 5 PSI...where did it go?

Alright so Ill start by saying tom has been tuning my car for 15 PSI. Doing a log today on a new tune, I am only seeing 10 PSI... WTF? Ive done a glance at things and I dont see anything out of place

So this is where everyone else comes in. Ive herd of a leak down test but I have no idea how to go about doing it and if i even know what im talking about for that matter lol

anyone have any ideas?

Im running Toms kit, evolution wastgate, greddy BOV and greddy spec II EBC.

Ive tried turning up my EBC up just a bit to see if anything changed and nothing new.

OH last thing, when I do hit 10 PSI I will see my boost gauge "flutter" but not very much. just moves fast up and down and stays really close to 10 PSI.

help!!

is one of couplers not tight? my guess is through the IC piping and you have a leak there. maybe a hole in the Intercooler?

Maybe your turbo went on a diet????

Sounds like a definite boost leak.

well I just did a test that tom had me do. Its not for the faint of heart but I unhooked my WG and do a WOT run. I watched my boost gauge and I went straight to 15 PSI at about 5-5500 RPMS. So I know my turbo can make it and my WG is sealing.

So either Ive got a leak somewhere in the plumbing or Tom has also suggested my BC could be acting up. Ill start with the piping and work my way around.

Toms comp turbo.

If I do have a leak, wouldn't it be late?

I've had a coupler thats been giving me problems...it likes to pop off when underboost. I thought I fixed it but I'm wondering if it's giving me more trouble. I'll check it tonight when I get home.

I will concur with above. It sounds pretty big if your only making 15psi at 5k. Esp on that turbo.
