I dont know what exactly went on with the wastegate. i was just told they welded my external wastegate onto my internal wastegate. but i have my external wastegate in my garage and i do not see ANY sign of any welding what so ever, unless they did That good of a job where its impossible to find a welding spot. As far as the offer, thanks alot man. i wish i would of thought this thru a little harder. i figured i could trust a performance shop over someone installing in my front yard. but nxt time ill make a better decision.
