I'll start things off...

My setup:
2005 EJ205
Blouch 8cm^2 18G
DW 740s
Walbro 255
STi TMIC
TBE
Perrin EBCS
GMS Turbo Inlet
Stock airbox
Stock headers

My tune is not all that aggressive IMO. I am running 21psi, 11.1 AFRs, and 19* at redline (12* at peak torque).

I am currently experimenting with disabling Closed Loop Fueling and running entirely in Open Loop.
