I keep losing boost on MY96 WRX. It has induction and full decat and was running 12psi standard, all day long. I have since fitted a dawes device and set it to 14/15psi, no problems.
The other day, i came out of a side road, booted it, fine in second, then in 3rd 9psi. Next day on the way to work, 14psi again, all the way. On the trip home, down to 9/10psi again. No boost gauge problems, so can rule that out, as the car feels like it is boosting less
Whats going on? Shall i take off the dawes and run it standard, or can anyone offer a novice some advice
Thanks in advance
