Where did you get tuned?

Vacuum leak or boost solenoid failure?

03wrxwagon · 2010-07-18, 11:13 AM

tuned by mayhem

i dont know if its a either but i started to think it was the stock boost controller and i dont have my leak tester with me..but it all happend the next morning in sac and is still doing it

Is this your first time to lower altitude since your tune?

That sounds like wastegate spring boost which I think means solenoid or the ECU not in control of it.

CEL? Flashing cruise? Any codes?

Forget the leak idea I think. The solenoid bleeds vacuum, so a vacuum leak would cause over boost if I am remembering correctly.

When you say that it went into limp mode, what do you mean exactly? Try swapping boost control solenoids with somebody.
