Can someone elaborate as to why Edge suggests not using Level 2 while towing? Is this purely a precaution against tranny damage, or is some actual reason why this isn't a good idea. As a sidenote, I have done it with no ill effects, but I'm curious. With the stock DMF, Level 3 is out of the question.

I tried towing with my Edge EZ on level 2. It was okay on level ground, but egt's climbed too high when climbing mountains. In level 1 on a 5-6 percent grade with my 9200 lb trailer in tow I can keep egt's under 1250. In level 2, they will climb up over 1300.

Good info, thanks.

Ditto to Roy W. Pulling little more weight however but similar results.

All good info, thanks fellas. I have yet to see any EGTs around 1300, but normally do not pull on Level 2. I pull between 10,000 and 22,000 normally.

I am also running the Edge EZ.

Have any of you noticed any mileage increases in level 1?

Nothing specific about the EZ but 1300° is not that hot. My truck was pushing 1575° totally stock pulling a 28'TT through the mountains - not often but it did get there. If I wanted to tow that trailer and keep it below 1300 I wouldn't have got over too many hills without dropping to 30 mph.

When I tow in the mountains, typically at speeds around 55 mph (not interstates) I take the transmission out of overdrive. I found that by towing in the mountains in Drive at speeds less than 60mph, that I have much greater throttle response, and hit the bottom of the mountain faster and pull it without as much strain. More strain equals higher egts. Using Drive in the mountains also creates more engine holdback and requires less brakes.

I've been wondering about that. We tow over a 4200 foot pass pretty often. Our trailer is about 13,000 lb. With the Edge EZ plugged in, I can easily get the EGT's up to 1500. With it unplugged, the EGT's stay around 1250 or so up the pass. Aluminum melts at 1226 degrees. We've got aluminum (alloy) pistons and heads... What is GM's max allowable EGT?

1350 for an extended period of time is as high as you want to go. Short spikes above that won't hurt anything but they shouldn't be sustained. Some on the board have pulled for extended periods over 1350 with no problems but the general rule of thumb is 1350 is max.

no noticeable difference in mpg with or without edge ez level1/BS combo compared to stock.But I get up hill much faster towing. To busy having fun in 2-3 so I know my mpg are suffering.Its a tow rig anyway.
