Question.., the exhaust fumes are pretty strong and the truck smokes a bit when taking off from a stop or under pretty good acceleration. I'm surprised that it smokes as much as it does given it supposed to be running a stock tune (per the installer) via SCT X4. FYI, EGR has not been deleted. How much smoke is normal? Should I be concerned about the exhaust fumes? I have no experience with these so I'm looking for thoughts from those who do.
The truck is used primarily for towing, therefore it is low mileage...about 64k. The MPGs and performance from stock is remarkable!
