O ok i was just joking about having the turbo suck air from the air box, and having it collapse like a juice box... hehe

As I'd expect from a man with a Black Regular cab 2wd (the best way to have a truck) . You're doing it right and I'll be excited to see it when it's whistling again.

Sorry to hear it let go but,......that would have been great to accidently do on the street. 775 lb/ft at 4500rpm. It never would have stopped pulling

When I had the truck towed home, I didn't get a chance to look at it. Rick at synergy told me over the phone that it looked like the engine blew, and would not start again. It had smoke coming out the exhaust and motor. I looked at the truck this morning and noticed that the fuel pump was not working. I checked my fuses for the fuel pump and they where ok. I start going over the truck with a volt meter and notice I was not getting any power to the pumps. I looked at the stock fuses, and ecmb fuse was blown. I pop 30 amp in there and it starts up like nothing was wrong. I checked my spark plugs and they looked excellent, even the number 7 looked really good. I will post a pic of it. Oil looked good and brown. Water didn't have any oil in it. Drove it around the block and found that I am in love with SD tunning or what ever Rick did. The part throttle is so much better. Rick said, he only has like 13* timing in it and its pulling like that. (678hp) It needs alittle more tuning but the truck drives excellent. I dont have the back firing as you let off the throttle any more. I love it. Here is the #7 spark plug.
