I didn't change the programming in the PCM for a turbo, so when I'm not in boost it doesn't know it has a turbo on it.
I get better fuel mileage now.
That's cause and effect.
Yeah, I already told you guys WHY, but apparently it was supposed to COST me fuel mileage and it didn't. I don't believe the efficiency changed one single bit when I'm not in boost.
you already said it was cuz you started [Edited by Moparts - Family Friendly Site - Keep it clean] footing the truck vs how you drove it b4. That's a different argument that states changing your driving characteristics can actually effect mpg. Anyone going to argue that one and say that there's less pumping losses at WOT so you should get better mpg by hammering on it?
