so for a little while ive had an issue where at startup my boost would flare up, occasionally too the point of stalling but after about 15 seconds it would calm down and be normal until the next startup, but today after a particularly aggresive u-turn it started to do it at every stop light i came to and stalled a few times as well, im guessing either some kind of vac leak, iac, or BCS which i recently took out and put back to get a part number, and the problem seemed to start after that, btw is the bcs also reffered to as a 'supercharger bypass valve' or something?

do you have a check engine light on ?

well yea but iuno if its related, my maf sensor went bad and has been unplugged for awhile, that sets off a check engine light and turns off traction, i'll have to scan my codes to find out if theres anything else

Sounds like you have more going on here. Check the connector for the BCS, and please scan. A maf shouldn't have anything to do with a TC light.
