So I test drove this STI today, for the second time now actually, and I noticed it was only hitting about .08 mpa, and really hovering around .06 most of the time. A stock 05 has I think 14.7psi or a full bar/ .1mpa.

So is this to be expected for a car with 78K miles on it? I calculate .08mpa to be about 11.2lbs, and that's at peak. Most of the time it's probably making less than 10.

Other than this the car is mechanically tits. Oil looks clean, all fluids have been changed out, new timing belt, alignment, motor is even clean. New clutch too.
