Binary boost - 200TQ10V - (1) it boosts or (0) it doesn't :-(

>I never know if my totally stock 200TQ will boost or not 

>Sometimes I get a healthy 1.4 bar and I can keep up, if not surpass many newer
>vehicles. Most times; especially on warm days, at WOT, I dont
>get more than 1.1 bar. When this happens, it seems to help if the car is 
>idled temporarily (like taking it out of gear on the highway 
>and coasting for a bit), then accellarate again. Then I will sometimes
>get 1.4 bar again, but only temporarily maybe for a 5 second shot, 
>before it bogs again.

>After this happens, Ive tried flashing out error codes based (car 
>still running), but all I get is 4444 - perfect right? I have an MC series ECU.

>The turbo pressure hoses all seem solid, althought I havent gone through them with a 
>fine-tooth comb. What else could it be after I examine all the hoses and IC end caps... lose 
>turbo impeller?!?
