Hey guy's, I'm new here and my question is this: I have a 02' HD2500 Duramax/Allison with the standard juice installed. I have no other products installed such as I read in here about EGT or exhaust. Am I causing damage to my truck by not having these other products or are they just monitoring systems? Should I remove the juice from the truck until I get them? I have been running the juice for about 15,000 miles with no problems that I know of! Please help! I love the extra power and especially when I'm towing my camper. I have it programmed to only give 50 more horsepower when in T/H and the full 90 when T/H is off.
