I live in Salt lake city Utah and Just bought a 2007 WRX TR with 23k miles that is completely stock. Always with 91 octane
Just started noticing yesterday that I may not be reaching full boost so i thought i had better ask about it for what the Subaru dealership mechanics said is completely different from what i have been reading on forums.
The issue..?: Max boost reached at WOT in 2nd-4th gear is right around 10 psi
Google Answers: Max psi for a stock 2007 wrx should be right at 1 bar or 14.xx psi.. Except for in first gear because there just isnít enough load on the engine.
Subaru Dealership Mechanic Answer: Max boost should be .7 bars (.8 on a good day) in any gear at WOT.
The only ďmodĒ I have done is the Snorkus Delete and a drop in K&N filter.
I have checked over all the vacuum lines I can find and they all seem to be in tip top shape. I have read there could be an issue with the boost solenoid or that it could have a vacuum leak. I have a Prosport Boost gage and at idle it sits stable right 23inHg.
The car feels like it running strong and boosts right up to 10psi in a hurry but then nothingÖ.. Is this normal? Oh, the car has never thrown a CEL so I really donít think itís in limp mode.
Please guys give me some feedback, Iím quite concerned about it and worried for my engine.
