First of all welcome to the org. When your turbo and oil is cold your truck will sound different. As you know, different metals expand and react to heat at different temperatures at different times. I have noticed the same thing with my truck. What is the smell like? During the "warm up" mode your EBPV is closed to attempt to heat your engine up more quickly. By doing this it is actually restricting the amount of exhaust that is actually exiting your vehicle (to heat it up more quickly). If your truck is in "warm up" mode you do not want to drive it hard or you can float a valve. I hope this helps bud
