My 2006, with 15,000 miles, has so far been a great truck. It’s never in the shop, except for normal maintenance, but is there a way to make the truck "more responsive" off the line during acceleration. Now I know that these engines exhibit a decent amount of turbo boost lag, but I'm not talking about that issue. I'm talking about the engine's rate of "spin-up" upon pressing the accelerator pedal. I've read other posts where people have said that Ford programmed the 6.0s to gradually apply fuel from idle, regardless if you gently press the pedal or mash it to the floor, to meet EPA emissions standards. I know the 6.0s weren't always like this because I remember test driving a brand new 2003 6.0 (a month after they came out) and that version of the 6.0 was very responsive. I've asked the diesel techs at my dealer if this issue can be rectified and they all say that it is running "normal". Just wondering if a tuner could help.

Thanks

a tuner would help. 03's generally spool up faster then later models I think because of the 10 fin vgt.

tuner on the lowest HP program, the "safe" one, fixed that complaint for me.
It gave me the throttle response that made my engine run like Ifelt it was supposed to at lighter throttle. Certainly makes it run better at higher throttle also.

the new edge evolution helped alot for my brother. I put injectors in and wow big help for me.

Wow, sounds good. I guess its now just a matter deciding on a tuner. I think I may go with the newest SCT and hopefully they'll be able to add pilot injection (active at idle RPMs only). If not SCT, I think I'd give Edge a shot, since it worked so well on my 2004 Cummins.

Thanks everyone

Remove the manifolds, turbo y-pipe, the downpipe and the EGR up pipe. Mod the EGR up pipe and the y-pipe then have all the pieces cermaic coated. If you can stomach it remove the turbo and disassemble it, have the exhaust side ceramic coated as well.

Geta Power Elbow, and SCT tuned for your truck then enjoy the ride.........
