I have a 2004.5 D/A LLY so I know that The Juice w/Attitude is not available yet. However, my question is; do I need to be very technically oriented to get one? I understand basic mechanics but nothing regarding a diesel. I like the idea of Juice, but I don't know if I have the technical savvy to support this kind of addition. I know the install is easy, but do you have to do a lot of diagnostic stuff to know if it is working properly? Also, what does it do for gas (diesel) mileage? Do I have to reset any factory GM settings before putting it into the dealership for service other than disconnecting the box? Any info. would help. Thanks.

plug it in, watch your egt's, be prepared to stock up on rear tires, and enjoy!http://www.dieselplace.com/forum/smileys/Big Smile.gif


Oh, BTW if you get anything over a 125 hp look into modding the trans or be very reserved on the pedal.....very few of us seem to be able to follow the latterhttp://www.dieselplace.com/forum/smileys/Evil Smile.gif


on edit no resets before dealer, just make sure you don't go in there with it. Gas mileage will go up in the lower two settings cuz engine has more power and takes less to move it. But when you get to the upper levels all the fuel going in drops it. Edited by: DURAMAXED03

Thanks for the info. I have a followup question. I have the stock exhaust from GM. If I do make the move to The Juice, is it necessary to upgrade? I've been seeing postings about 4" stainless. What would be the advantage of doing this? I can't imagine this would cause any problems with the GM warranty, but any info. would help. Thanks in advance.

You'd want to get a 4" turbo back exhaust. with the greater flow spent fumes out the tailpipe it lowers the all important egt's. You have a stock exhaust and stock intake you're not gonna get as much air to all that fuel and it's gonna cause heat. High egt's can ultimatley cause damage to your turbine blades of the turbo and from there it's bad berries! Stainless is great if you don't mind paying 600-1000+ depending on vendor. Aluminized is suffcient but doesn't shine up and or last as long as stainless. I'm no expert but this is what I've picked up reading what the pros post on here. P.S. pay attention to Mackin, Hoot, Kennedey, Mike L. These probably will forget more than I'll know bout how to make a diesel run good, how to maintain it properly, and almost anything else you could think of! Exhaust shouldn't affect anything warranty wise on your truck if it does find another dealer fast! hope this helps.

The biggest PITA part was drilling and tapping the manifold for the EGT guage. I used the Hoot method. It was much easier than I thought.


I run around on the 90HP setting and have never limped or slipped the trany. The juice is addictivehttp://www.dieselplace.com/forum/smileys/Evil Smile.gif


Milage is directly proportional to your right foot with the juice, although I bet if you get or any tuner your milage will drop like a rock since its really hard to drive nicehttp://www.dieselplace.com/forum/smileys/HiHi.gif

Drilling and tapping the exhaust manifold for the EGT probe associated with the Attitude monitor is not something I'd recommend for a first time project...http://www.dieselplace.com/forum/smileys/Ermm.gif


Especially if you don't already have the tools you'll need. I've checked a couple of the local shops and gotten prices which didn't seem too bad, but since I already own the necessary tools I think I'll do it myself when the time comes. If you had to buy those tools, then the price of the install is not a whole lot extra.


The only other thing is to be careful when working with the wiring harness plugs. The pins inside those are pretty delicate, but as long as you are careful when installing them, you shouldn't have a problem with those. Bent pins have been a somewhat common problem noted here with Edge installs.

It probably wouldnt hurt to put some eletrical grease in the connections to help ease the installation, and to keep the pins from oxidizing.

Personally I thought that tapping for the pyrometer was easier than routing the Attitude cable. If it makes you nervous you might want to practice on a piece of mild steel first. Just make sure that when you start on your manifold you use a sharp tap. --SS
