The boost will drop off as the turbo runs out of steam in the higher rpms. A IX will usally taper to 22-23 lbs by redline. I'm not sure how soon it starts though.

According to Mike @ AWD the boost will hold longer with an 02 dump and HP actuator. I will be getting both items to see if he is correct. He said the taper should be 3-4psi with those items, so if I ran 30psi I should see 26-27psi at redline if he is correct.

Best I could get with my 04 RS on E85 with a IX turbo on 30 psi was 395hp, on a Mustang dyno. Uncorrected was 389. Tried everything to keep the boost from dropping to 22 psi. Best I can get it to hold is 23 psi at 7500. Stock motor. Cams. Stock intake and TB. BR exh, Race core, lower pipe. Stock upper. Pump, 1000's, ported manifold, Ebay O2 housing.
I have tested a few of the O2 dumps, four different heavy WG canisters. Regardless of what people advertise or claim. Have yet to see anything that will make a IX turbo hold 26-27 psi from a 30 psi peak. Turbo dies off up top period. Most cars drop to 20-21-22 if you are lucky.
