I have Mach 6.5s and the only time they haze at idle is when the truck is cold.. Once warmed up they do not haze enough to see at idle during the day at all! At night pulling into a gas station or something in the lights you can see a very slight haze... Love these sticks!

More power, run cooler, less smoke than my Jammer 150s

I should have said that in my first post, my truck only does it when the motor is cold, once it has warmed up, no more haze.

Perfectly normal then... When cold combustion is incomplete, engine is way out of its efficiency range... Let her warm and all is well!
