My first turbo car was a 94 cummins 12v. Single cab dually, 35 gallon tank, 19mpg no matter what I was doing except for stupid heavy loads.
I got pulled over twice in it, never got a ticket. First time was a BS pull over thinking I was trafficking drugs... since I commuted a lot from GR to Flint for school apparently. 20 minutes on the side of the highway wasted.
Second time I just got done doing a bunch of maintenance and fixed the AFR on the fuel pump after my buddy screwed it up before he sold it to me. I smoked out a cop at about 9:30 at night. Hit lockup on the torque converter, shot to about 35psi, and jumped about 20-30mph in a few seconds. Pulled into the church parking lot, rolled my window down, and waited. He came up and saw me covered from head to toe in grease and soot from working on it, and after I told him what happened, he just laughed and told me better roads to do some test&tune on and to go back home. He complimented the truck before he walked away. I'd buy another one in a heartbeat... with less michigan rust.
