Everybody talks about definately getting gauges if you have a EZ... In my opinion, this may definately be true with the ETH since it runs hotter, but I wouldn't have any problems sleeping at night if I pulled with my ETC w/out my gauge (I have an EZ with the boost elbow). If I lost my gauge tomorrow and was leaving for a trip a couple of days later pulling my 12k trailer up from Phoenix to northern or eastern AZ up the 6 1/2 - 7% grades I would fix it when I got back or when I 'got around to it' (I would just wait several minutes before shutdown after a long pull). My truck runs atleast 200 degrees cooler around town and a *minimum* of 300 degrees cooler under extreme towing situations. I ran from Phoenix to Page, AZ last week when it was around 110 degrees in the middle of the day with my foot to the floor in overdrive (5 speed) going up the hills at 70... getting stuck behind a truck going 35... down shift a gear, put it to the floor... . pass the truck (still going up the same 5-7 mile 6 1/2 grade) up shift to overdrive again and continue with my foot to the floor. When I'm towing, my foot is always to the floor when going up hills. I was trying my absolute hardest and couldn't get my EGT past 1150 pre (about 850 post). I mean my absolute hardest!! Anything below this, my EGT would drop about 100-150 degrees. This is pulling a 12k. Stock, my truck (the gauges have been in for awhile) would sneak into the 1350 range briefly before I backed off on the throttle. Unfortunately the only times I pulled stock was in the winter so I could just imagine what would of happened in the summer! Also, when I saw 1350 I was going from Phoenix to Imperial, CA so I didn't have all the loooong grades that I do going up north or east. My truck drives sooooo cool now and I figure if anyone should have the gauges with a ETC engine it should be the stock ones!!!!!!!!!! If my truck drives cooler now than stock, I can't see why I could recommend that someone "definately" get gauges with the EZ and at the same time tell people that gauges were "optional" on a stock ETC.
