subarus seem to respond to AFR changes a lot more than evos. not sure why....i still don't advocate throwing extra fuel in- it usually means you are doing something wrong when you have to use fuel to cool egts.

12's are fine on 93 octane. i'm a fan of actually using the octane potential of fuel and minimizing pumping losses of the motor.
leaner is meaner
of course when i looked in my header while replacing the gasket, it was WHITE. like very WHITE. no black, no nothing, just white....
also, remember turco is still rocking the stock catback, so that kind of kills boost up top (i think dex can attest to this as well).

edit: I'm almost tempted to mess with my wastegate actuator... to bump up my boost, and see if it will hold boost better at red line.
and yes extra fuel is definitely a bandaid.

higher spring pressures are overrated- my turbo holds like 4x the base spring pressure with a hybrid MBC and 3 port solenoid setup. you can also use a restrictor pill if you need to.

Dex you need to get the GM 3 PORT!!!! Mike remind me to ask steve how much he wants for his, i may just buy it so i can force one of these crazyfaces to install it.

i know but i really really like how my boost works now. its essentially stock. plus a couple psi from the restrictor, and a bit more from the down pipe. if i can get a couple more #'s of preload to up my boost across the board (especially up top) i will be happy.

The lower the wastegate spring pressure is from your desired boost level the more likely it will taper
the stock wastegate is ok, but you run into a lot of taper at high boost. I used to run stock turbo at 32 spike 28-30 through some of the rpm band and then taper to 23ish
Some stockers I have seen taper to 17-19 from 28 or so
