after a few little tweaks to see if it fixes anything the car is still overboosting, and i smell oil, faintly, here and there. luckily i've found someone that happens to be good friends with a tech at a mazda dealership and he's gonna try and get it in there. he talked to him already on the phone and the tech agrees that its the wastegate, and the piston rings will be replaced if a compression test says so. can't wait to actually get it in tho.
