blue smoke
Hey you guys i have an early 99 7.3l powerstroke with a 4" exhaust, intake, terminator modified oil pump, and dp tuner. I noticed a few days ago under heavy acceleration when the truck is blowing black smoke it has a slight tint of blue. Theres no blue smoke when the truck is first started up or when it idleing. The amount of blue smoke increases with the higher setting of the chip. The smoke only looks blue when the smoke is disipating and light passes through it. Can you guys help me out? this really bugging me.
