Hey, ive got a 2000 BE5 Legacy - RevC
Got no CEL, but sometimes under boost I only get 7psi and a different sound out of my exhaust. Normally id get 15psi on both turbos, done it for 6months or so but its starting too annoy me. the other thing i noticed is secondary normally comes in at 4500rpm but when its down to 7psi it comes in at 5000rpm. any ideas
Ive replaced air intake pipe, o2 sensor, spark plugs, coils, intake manifold gasket ect.
Runs 110% when its boosting the 15psi best car in the world to drive then boom it cuts to 7psi. tends to be under load, eg; 4 or more people in the car or 5th gear up a steepish hill
