I just ordered one of these dumps. I have been unable to run as much wastegate preload with my current Green setup as I would like. This was with an unported 9.0 turbine housing, a FP 18# WGA, and a SSAC O2 housing.
So, I'll be porting my Green's 9.0 housing , and installing a Forge WGA, in addition to the new O2 dump. I hope to be able to get my Green to spool to 23# by 2800-2900 RPM. Currently, I see 23# by 3200 RPM.
EDIT: Sorry, but I won't be able to provide comparative dyno #'s, as there are no dynamometers in my neck of the woods. The best that I'll be able to do is DLL's.

What sold me on it was the larger diameter of the turbine exit pipe when compared to the other aftermarket O2's on the market. This has got to be beneficial in helping to reduce exhaust backpressure.
The sound factor of the open dump doesn't excite me very much, as my Buick TurboRegal had dual Deltagates located on the underside of the crossover pipe dumping straight down about 4" above the pavement, but that's another story.

What kind of gains would you expect to see using the EPM dump compared to the Buschur SS O2?
Mods:
Buschur catless TBE bullet
Buschur intake
Buschur MBC
Buschur UICP
Tuned to 320whp.

EPM 02 dump FTW! About 5k miles before their 02 dump came out i installed a ported and coated exh. manifold, 10.5 hotside, and Megan 02 housing. When this came out and i saw the dyno gains and heard the video clips i knew i had to have one. Even though i only put the other stuff on 5k miles on i took it all back off and installed the EPM 02 housings and i'm very glad i did. Butt dyno alone noticed a huge difference over the ported and coated megan unit. And WOT this thing sounds mean!!

You guys make me proud....!....all of you are awesome customers....
And Mike at AWD is the shop to go to when you need the EPM O2 installed and Tuned...they are pushing the envelope on the stock turbo...just look at all they have done for the Evo community running the stock frame 9 Turbo. The numbers don't lie. Most Wanted and others --> pushing their Evo's into the 10's on the stock 9 turbo along with the EPM O2 Housing.....can't wait to see what the future holds...why would anyone spend big $$ when they can have the 9 turbo beatup on these pricey GT turbo's...?...

I just installed my EPM o2 dump yesterday. I definately felt a increase in power through the mid range according to the butt dyno. The sound is just UNREAL. I cant describe it. The videos do not do this part any justice. You have to hear it in real life to appreciate it. The best part is it sounds just like any other evo with an exhaust when your off boost. Also i want to give props to Q and the crew at EPM for making a great product and providing second to none customer support/service!
