I have a 2005 GMC Sierra 25OOHd Diesel. I put a banks six gun shooter kit and a banks 3 inch exhaust. The only thing that i noticed lately is that since the switch to the low sulfer fuel that my fuel economy has droped alot. I use to get 22-24 mpg on the highway going 75mph now I only get 14-18. This new fuel is lously.
