I have the Egde Juice module with Attitude installed on my 2003 Duramax (LB7 engine). It works as advertised. If anyone out there is familiar with the Shirwin Grade ( I believe its called) it is a long brutal grade leaving Bishop California toward Mammoth Mountain. With my travel trailor (6000 pounds dry) fully loaded and truck bed loaded to the gills, I pulled the grade in over drive averaging over 65 mph. A couple of times the Allison 5 speed transmission dropped out of passing gear to 4th gear for a minute or too. Oh on another note, I consider myself pretty handy with tools. But dispite the advertisements it takes longer than 10 minutes to install the module. It took 20 minutes to install the temperature probe and about 15 minutes to install the module itself.

The exhaust gas temperature (EGT) did hit the suggested 1350 degree temperature set limit. But I have the Juice module setup to immediately start de-feuling to bring down the temperature. This however worked marginally. The trick was to step on the accelerator to drop out of passing gear (or manually shift) to 4th gear and the temperature immediately drops several hundred degrees.

Another example of the difference the module makes is when I pulled out of June Lake Loop to go back toward Bishop there is a what I estimate to be about an immediate 8 percent grade where you must merge into traffic where every other rig is racing to make the grade. In level 2 (do not use any setting above 2 while towing) I was immediately up to 65 mph but blowing a lot of black smoke. That scared me a bit but from what I understand that shouldn't be a big deal.

I do have a major concern however. I found that even with the Edge Juice module set at factory settings (turned off) according to the EGT probe, I would hit the maximum temperature of 1350 degrees when climbing steep grades. Before getting the temperature probe installed I never saw or knew the temperature of the EGT. My question is: what temperatures should I be really concerned with and do I have an issue because I'm hitting the maximum temperatures without the module? By the way, I only turn on the module when I need the power or leave it in economy mode.

Is there anyone else out there that has the module installed and has anyone had warranty issues with GM? Edge Juice user manual suggests you remove the module when you go to the dealer for service. I think I'll remove the module and use it only when towing my trailer.

Lloken. :cool:

Thanks for your reply

I'll take your advice and back off the throttle. You make good sense. I will get the exhaust done soon. Would you please explain what the cold air intake. I was thinking about mounting an electric fan on the radiater but I get the feeling it's not the same thing

What kind of issues have you had with warranties?
