Noticed a couple months ago when pulling my blazer with a superchips tow tune that my egts were definetely getting warm. This was pulling a good sized grade at 100*so i didnt think much of it.
Fast forward a couple of months and after doing some testing and playing around with different tunes for some reason im still running hot even unloaded. With a superchips towtune loaded i can hit 1300/1350* with the truck empty, Loaded a hypertech max energy level 2 tune and im able to hit about the same with it at wot with the truck empty.
My truck never used to run this hot on tow tunes. If i remember right about the highest i could hit was 1200* empty at WOT at like 90mph with the superchips tow tune loaded. Both the superchips and hypertech supposely are "EGT safe" tunes and hypertech even says you can tow on any of the three levels without worry.
Troubleshooting ive done so far...
-Cleaned the air filter on the sb intake
-Took the MAF out and sprayed it down really good
-checked injector balance rates(highest are -/+ 1)
-loaded the hypertech tune to see if there was a problem with the superchips tune
Anybody got any idea's?
