Anything in particular you're wondering about? You can put your hand on the blankets after running the truck about as hard as you want. Fixed geometry turbo's usually see a small boost increase at WOT. Underhood and Intake temp drops of 20+ degrees. Cruise EGT's tend to run slightly warmer but typically WOT EGT's drop.
On stock stuff, doing blankets or wrap on up-pipes and turbo will net you the most gain. Didn't get a noticeable impact wrapping the stock manifolds. Aftermarket manifolds and headers tend to benefit from blankets though.
Thanks for the information, how thick are your blankets for the up pipes, I am going to build 2in up pipes without the flat spot, so I need to get an idea of what I need to make my four inch downpipe still work.
