Ok guys so I'm new to this site and I'm a little confused.. I got an 08 6.4 intake egr/cooler delete 5" dp back exhaust and a spartan tuner. I'm currently running the 250 tune...

So here's my dilemma I ran the truck hard today from red light to red light and then when I was stopped I noticed a burnt oil like smell and there was a hazy smoke coming out my passenger wheel well area near the exhaust. It was really strong at first and then it started dieing down. Till it finally cleared up. My temps where all the same as they usually are. This is my first tuned truck so not sure what that was any help would be appreciated

 

So I found the problem my rear axle seal was leaking and must splashed some on my rotor hit the and burned it....Happy it wasn't nothing major
