get this one...I took my 12v into a 3-man Tranny shop to have them put in a triple disc T/C once.As i am coming back to pick the truck up {2 miles from the shop}..i see a HUGE death cloud and think, wow someone's got a smokey diesel truck i wonder who that could be{since there's 20 cars in front of me and can't see what's making the smoke yet}..every stop light for a mile the cloud would engulf the cars behind it and me ..the last few stop lights i see white tire smoke as WELL as black smoke.Soon enough MY TRUCK comes into view in front of me as i head BACK to the shop in my buddy's little car ...i follow the guy driving my truck right up and see he immediatly shuts it off and runs inside the shop.The owner said "oh noooo, my tech would NEVER treat a customer's truck thaaaat way!" sure whatever...i then go to the tech and pretend it's not my truck he just drove..i said "hey man, do you know what is in that truck, looks like fast and smokes alot"..he says"no, but the whole freakin' rear axle jumps like a fish out of water when the turbo kicks in, i did it 6 times, it was cool, only the old camero i used to have did that, not a diesel truck" ...i was so stunned, i had to leave...he freaked when i got in the truck and left..
