like i said in the other 6.7 powerstroke thread if pilot injection does not have a performance purpose i wish a tuner would get rid of it so that clatter is there again

 

Why make it quieter? it actually makes the truck sound like a truck!

 

Because all the town living former minivan driving soccer moms and the town living yuppies who don't use their pickups for their intended purpose complain

 

Stupid people -.-
