wow its been forever since ive posted on here.
lets get the basics out of the way first. 2002 wrx, catless uppipe, catless 3 inch turbo back, 16g, previously tuned for stage 2.
now for the details. a guy i work with recently did a hybrid swap to his 2002 wagon and got a brand new 16g for the build. well lets just say money got tight after the build, so he sold it with the stock td04. lucky me i got a brand new 16g for nearly half price. last saturday i swapped out my td04 for the 16g. now the only thing i have not done, whick i know i need so stop the flaming now, is hooked up the boost gauge ive had for a year and most likely a MBC. whats happening is during normal driving everything is fine, but hard highway pulls the waste gate sticks wide open. and by open i mean 180 degrees wide open.
the only thing i can think off the top of my head, is im building too much boost for the wastegate, and its getting pushed open so hard its swinging to far. now yes, a MBC will correct that by dialing down the pressure so the wastegate can do its job properly. i just wanted to get some input so i know weather or not im heading in the right direction. thanks in advance!
