Can't complain about my 05 LLY. Great performance and very good fuel economy. Quick question though - how much smoke should I see. If I jump on it hard, I can see a very significant black cloud behind the truck. Doesn't fog the whole road but leaves a definite smoke pattern out the right side. I thought there was suppost to be very little or NO smoke. Truck is bone stock and never been to dealer except to check steering.

Is this normal? Thanks for the input.
