I have the standard Juice and tow a big a$$ goose neck trailer out of the Phoenix valley in the summer. Towing on level two I have to keep my eye on the EGTs to keep the long big grades under 1400.
I never let my wife drive unless I back the Juice off to a stock setting. She surprised me the last trip she made to Payson AZ when she got back and told me that she "drove like you do" (meaning foot to the floor) going up the last steep 5 mile grade. The EGTs got to "almost 1500" before she backed off the throttle! (see why I don't let her drive my baby Juiced?)
I have been pretty concerned for some time that the stock configuration might let me get too hot to do damage (before I got the EGT guage), but Chevy can't tell me what is too hot. Naturally, when I drive this beast I want to do the speed limit regardless of what I tow or what the grade is, and for the most part I do, but, even at stock setting when is it too hot for the turbo?
The hot rodders that do the 12-15 second runs are making a shut down at the end of a burst of heat, but for those of us that tow heavy on long grades and reach high temps (1300+) how long before we have a melt down?
Inquiring minds wanna know!
