yes i can vouch on 100% throttle and in drive the car accelerates and boost reaches 9 or so and with wastegate line attached it only reaches 5 on wot... -- paul its possible if u have no downpipe u will have very slow spool due to no backpressure but i dont think thats the case because there is a connection === first i think u should remove the turbo and inspect the wastegate before you do ne thing --- hook the actuator up to a hand pump with a gauge and visually watch the gate open around 10 or so pounds. you need to do it with a hand pump so u can see it open and close as u pump. Once u establish that then move to leaks --- if u need a pump i can find one for u
