How do you feel about "coal rollers"?

Not sure how you would do it just for a look. I dont live in a city though.

I have seen switches to turn the horse power up an down though. Its good to be able to turn it down if you drive in to some states or if you let someone else drive your truck.

Yea I think it's more of a city thing, but this is the kind of thing I'm talking about:

Ok the low flow rate of the smoke gives it away. They are clogging the air filter on the non turbo trucks an wiring a switch to the waste gate on the turbo one. Both ways cut the intake air making the truck lose power an smoke like crazy... One or two just have blown engines.

Dumping a few things of motor oil in the fuel tank would work just as good without the need to break your truck. Then at least the smoke would come out fast enough to look right.

Here is a video where they say what he is doing. He disconnected the hose from the turbo to the intercooler. Starving the engine of air. Lots of smoke an no power...
