Not true but what do you know... you never deleted. You just get hearsay off the forums. I know several trucks that have been deleted and many picked up 4+ MPG on the highway and 2+ in the city and sometimes more depending on the driver. I can promise you... you will get better fuel mileage being deleted. Period.

And screw all these retards preaching federal law to you. It is your truck. Do what you want! Wanna know why I say that? I work on Ft. Rucker. Guess what the base workers (contractors) drive. F350/F450 6.7L trucks. Guess what they don't have. That's right! DPF or EGRs. They roll coal quite a bit. So basically the Feds preach "do as I say and not as I do" is bull****. If it is happening on Rucker... I bet all the bases have deleted trucks.

I'm trying to find out who made the tune that is in the truck I just bought, not that there is anything wrong with it, just want to know what kind of tune it is. It is on an SCT X4, and so far after owning it a week it is getting 19.3 MPG.

I do have to agree with the others on the smell, it stinks, and sorry about that. I didn't realize it was fully deleted when I bought it, it wasn't until I got it home and gave it a full once over that I discovered it had no SCR or DPF underneath, I just knew the EGR was blocked off. The good news is that it does NOT roll coal, if anything I have only seen a puff of gray come out under a hard get up and go on an on ramp. At idle though, it stinks, and I get an occasional whiff of it in the cab. Whats funny is the 99 7.3 I had did not smell this strong, just a light aroma of Diesel.
