    Red face Inconsistent Boost

    I've just got my first WRX; a standard 2001, but I'm ecstatic! My problem is the boost keeps restricting itself down by 50% every now and again, and sometimes it doesn't. I was told the comp. is putting it into 'safe mood'!? Any help from you WRX guru's?

    I have the standard boost gauge which comes with the car, showing your boost from .0 to .15 On a good day it shows I'm getting .1 but every now and then restricts itself to .05

    Is the CEL on? Does the car buck or run erratically otherwise?

    The CEL was on initially until I changed the fuel, and now its off, but the boost still restricts itself every now and then. I've just got the CEL report which says something about Fuel Trim malfunction. Fuel here in Kenya is pretty bad most of the time and very low on octane. Could that be the reason? Is there a ratio for octane boost to litres?
