Rut roh boost problem....

[Shortthrow]

It appears that my car doesnt want to boost into the black anymore and stays around the begining of the red.... vaccum lines?

bad plugs, DI going bad, poor gas, but do the vacuum check and fix first.

Hm... I only use 93 octane gas so that cant be it. It could be the plugs, considering the DI does the burn off almost 100% of the time when the car is turned off... unless it is normal for it to do that.
