ive been searching since january 2015.
Bought the 07 sti january of 2015, loved it since. The gauge it came with, has read max, 8-9lbs since day one, never worried about it to much until I did some research. had some sputter issues, thought it was a vacuum leak, better zip ties made it drivable again. Then more hard stutters, until boost seemed to have hit a fuel cut-off or something. Finally a CEL, misfire 303, changed plugs and coils, been fine since. Still hitting 8-9lbs on gauge. Ive read about the restrictor pill, felt for it, its not it there. The only mods that I know of are a blitz nur spec muffler, dont know if its just the muffler or turbo back or whatever? I am the 5th owner of the car, so I dont know what its been through or whats been done to, just a chance I took, Ive been doing cars for years, so when everything seems ok, I went with it, happy so far. Just wondering, if I buy new lines with the pill and put in, will i need a tune cause im doing something different? Or will it be fine and hopefully hit more boost better just by putting it in?
