Successful day,
Fixed the impreza + new oil change
Removed the SSQV(real) from the sti, <- drives soo much better, less rpm drop between shifts, stronger boost in low rpm, very reccomended do to. I forgot what full drive ability felt like.
Turbo doesn't spool as loud now, :( use to sound like a jet plane. But now I have wastegate chatter on high boost Maybe it was just masked by the ssqv before.
