[Blue05]

My 05 truck is smokin blue pretty bad at idle and while driving slowly, doesnt matter if it is cold or warm, i can come off a 2 hour trip on the highway, pull in somewhere, and after about 30 seconds its smokin blue again, its definitatly diesel smoke, i can feel it in my eyes lol. The filters are good, it's not using oil, and does it with or without the tuner installed, BTW it has 90,000 miles on it.
