    Trouble with turbo on 05 wrx

    I'm a new owner to an 05 wrx its an auto (bought it for wife) seems like it is really slow and wont build much boost unless you really step on it, don't seem like i'm losing or using any oil and i'm not sure if when a turbo goes bad you always lose oil or not in previous times i have. it also got down to around 45 mph when driving in the mountains in Virginia when it was on the floor. be happy to hear any ideas?????

    Are there any modifications to the car? Possibility it might have an incorrect tune for the current mods.

    Regardless it should not loose power or bog down like you described,with the pedal to the floor. Maybe something is impeding exhaust flow (broken catalytic convertor) or fuel flow.

    You should always use 91 octane or higher. Says right in the owners manual and fuel door. All you have to do is Google "convert MPA to PSI".
