Weird wastegate rattle situation
I know, I know, another wastegate question, but this one is a little different. When I start my car after it has been sitting for about 6 hours, I have no rattle at all. If I happen to turn the car off and run into the store or something and jump back in and start the car, my wastegate rattles. This only happens when I have already started the car within the past few hours. I know its my wastegate for sure because if I put my JB4 on map 8 (Limp mode) the rattle stops completely. I bought a new wastegate and was going to throw it in but I wanted to ask you guys if you have any ideas of why it does that.
