Yea def , after reworking some vacuume lines and fixing boost leaks I took it out and it spiked up to 6-7 psi and the front of the car was getting way lighter then ive ever felt iot get ha. The blitz BOV is LOUD at anything over 2 psi wayy louder then it was on my buddys WRX.
Octane adjust bar? Never heard of it. What is this?

Oh ok that makes sense. Im still getting used to trying to look at all my gauges while giving it some throttle. but looks like pegged 5-6 psi by 3500 i think with the WG open trying to keep from boosting anymore. Its internal wg came set at 8 psi but i turned it down.

The " dead end " plugs on the wiring harness . Liek ShoAmo said one is right under the coil pack. ( 3 deg pulled) and another over by the cam sensor ( 15 deg pulled ) from the timing if i understand it right.

Here's what Probst says about it:
Charles O. Probst said:The Octane switch in some engines adds a feed-forward signal for spark timing and turbo boost [Ed. note: Boost comments are obviously not applicable for stock, or even turbo'd SHO engines, since the ECU doesn't control boost in either]. When the Octane Switch is in place in the underhood socket, it shorts the contacts in a circuit to the control module for normal spark timing. If the engine is knocking with the fuel being used, you can change to a higher octane fuel, or you can remove the switch from the socket to retard the timing by about 3 degrees, and reduce the maximum boost [Again, boost comment is not applicable to the SHO engine].
Bob Stelmaszczak of Ford SVO (Special Vehicle Operations) told me of the beginnings of the Octane Switch. In qualifying the Ford original 2.3L turbo to California regulations, he ran up against a requirement that the engine control provide for operation on regular fuel. The turbo engine was set up for premium, and it was pretty late to change the engine control. Simple solution: The Octane Switch, which continues in current applications.

So today at lunch of work I was showing alot of the guys my car and fine tuning a few things ( bov tension ) changed 2 vac lines moved the filter slightly and tighted more clamps. on the drive home i goose it a few times and seems like the car is running slightly better then before. I lay into 2nd and it pulls harder and smoother then before nice. its a lil wet here today so first and second break loose way easy at 4k in boost, but it was dryer on the freeway.. I give 3rd 75% throttle and sec later tires broke loose at 65 mph ! I know its wet but dang that was a cool feeling ! I do have cheap tires but not bald tires PZ900's :/ gonna be needed a front set of good rubbber soon.
You need to get some vids up!

So stock maf, stock fuel, no enrichment, and the only 'tuning' is global timing retard of 3 degrees? Awesome.

yea it seems to be doing 4-5 psi steady in 1st and 2nd and takes longer to build in 3rd but i havent takin 3rd very far.
Any way to measure EGTs or WB02? I would be careful to do much high speed runs without those measurements. Welcome to the wonderful world of boost. Great stuff eh?

Im looking for a wideband right now, going to decide this weekend what to do order one online if I cant find one thru a work supplier for cheaper.
Yea I havent even takin the car over 70-80 in boost but a few maybe 2 psi in 5 , I dont plan taking it faster til I get the wideband and tweecer hopefully.
oh man is it good. Ive drivin alot of cars but duuuuude... the SHO motor boosted hitting secondarys is freaking awesome. :woo-hoo::woo-hoo:
