Smoke is annoying on a daily driver getting into while towing is like damn there goes my money out the tailpipe had power joke that smoked stupid and it gone to a clean burnin cummins now with a smarty level 1 no suit on my tip :) only a puff on start up :) fuel is to spendy to blow it all over the road lol :argh:

Four ways to make smoke
1. Plastic bag
2. Drive like granny for a month and then stomp it on a hard acceleration and roll coal
3. Run a Y line from your fuel line to a fitting on your exhaust and put an electronic servo for easy on off
4. Create HP and the smoke will come

The first three will get you hated and ridiculed because its us being honest. The guys that can roll coal because they've got the trucked tuned to race have earned it and don't try and make your truck look like that unless you've paid the price and hard work to do it Which is #4.

Even the guys with highly modded high HP trucks aren't gonna be blowing smoke if they can avoid it because it just makes the EPA and Greenpeace get their panties in a wad.
