I had the flutter issue at first but sam resolved it when he said he would and sent me parts at his cost to fix it. I had heat soak issue but that got resolved. I have a cold start issue and I am the only car experiencing this (Only when temps are at 20 degrees or below). I have to barely give a little gas to get it going. Sam is helping me out trying to pinpoint what it could be. But it does not affect the way it drives.
I am a 6mt and the power is nuts. Idle is fine. You CAN hear the intakes a little when at idle but not from inside the car.
