hi all

95 wrx import

as the title says when im driving hard in 1st 2nd 3rd everything seems fine.

but 4th and 5th i dont seem to get the same boost.

idle seems fine to.

ive fitted new plugs k&n panel filter decat center and back box.

i use optimax and millers octane boost?

should i be getting the same boost through all of the gears.

thanks all.
