I did notice that the lights go dim when I hit the horn now. I'll look into that. I definitely don't want any problems down the road....

Thanks

 

You aren't saying this has something to do with the EGR are you?

 

Nope. Just getting a bit off track here....

You know, I got my weekly CAT FULL message this morning and when I read my codes there were none for the EGR. Only one code for each of the three banks of the Exhaust where the foolers plug in. That's strange because I thought I shouldn't be getting any of those codes anymore.....

 

It is strange Mike. . . I haven't driven it that much since I did the delete. But once I gave birth of the baby, everything settled down to normal. No messages

Something isn't right there. PM me your email address and I'll send you some voltage reading to take at the ECU.

That has nothing to do with the EGR delete

 

I've been getting codes like this since I did the deletes. Just not all at one time. I'll contact H&S if I have any problems due to this. I'm not too worried about it since the truck keeps running fine and mileage is still up.....

 

You'll have to bear with me because I am new and you don't know me.

I tend not to get too technical on the forums unless I have too. There is also a thing called TMI, which I try to avoid. I also try not to assume anything. So if I sound like a Putz. . . Not really. . . 90% I know on this new crap, I just don't tell anyone. . . I have a life too.

I do love to Lab Rat stuff though. . . . While a few were running around with the EGR's unplugged, the question was still there, will it harm the DPF cats. I proved it would not. If anything, they are cleaner than ever. My next trick will be to put the primary cat back in in the flange and leave out the dPF. Then I will let the black box keep the regens in check. I'll look at it in another 8,000 miles then. When they fell off, they were clear as I expected with over 400 since last regen

 

I can't help you with the H & S. No experience

 

Wow I have learned alot, but what can i take off my 07 5.9 to get 2to 3 mpg better thanks.

 

No your not a Putz, I guess I didn't quite understand what you were doing. I didn't realize you were still regening. I applaud you for doing one at a time and making the case. I however am not that patient. I just RIP IT ALL OFF,,,
,,,,,AND LET ER BREATH!!!! Oh, excuse me, heemmm. Sorry, guess when you have two pre teen girls, a house to keep clean, 2.5 acres to keep tidy and running and then a small diesel shop too, which is where I really want to be all the time, it makes me a bit snappy!!!!

 

Not to sound like a wise guy. . .what is the title of this thread?

Start there. Then do a Cold Air Filter and remove the shield in front of it by the condensor. Then the DPF has to fall off. . . Suggest BADP for that. Total, that will give you 3 to 4 more MPG

 

Thank you for being that wise guy, this has been won of the better threads that I have read.Thanks again.

 

He's got a 5.9L, bud.

2 to 3 mpg better is going to be much harder for you than for the 6.7L owners, dude. You already get better mileage than most stock 6.7L owners. I would start with a free-flowing exhaust (either a cat and muffler delete or a full turbo-back exhaust), a good CAI, and a programmer. If it were my truck I would go with a 5" TBE (for the sound more than anything else) and a Smarty and call it a day. I live in dusty conditions so a CAI is a no-no for me. Just my $0.02 but you might want to try the 5.9L section for more information on that kind of stuff. The "2007-Current" section is for the 6.7L crowd, the 5.9L information is in the "2003-2007" section.

 

He thought you had a 6.7L. Your 5.9L doesn't have an EGR to unplug, nor a DPF in the exhaust.

 

Thanks for the help. John

 

The only things I ever found to raise mileage in my 5.9s were 40hp injectors, better torque converter, engine breakin and Quadzilla boxes. The Quads always gave me a 1 mpg gain on my 03 and 07 trucks.
