i readjusted my volvo 760t's waste gate. to build more boost. i am making more but now the car dosnt know when to be on or off boost. it bucks when the cruse control is set or when your at a steady speed. the turbo keeps boosting up then droping off. its very anoying. its liking the xtra boost but . i would like to know how can i adjust my turbo so that its dosnt want to be sooplin up all the time. its fitted with a t-3.

 

Do not ever mess with the wastegate.
