I have a 05 2500 duramax and im pulling a 30 ft camper. my truck is stock so do i need to get some gauges to watch my EGTS, and boost? the muffler was cut of when i bought it. Im assuming it had a CAT but its not there anymore. I also have a Diablo Predator tuner that has some tow tunes would those really help me for MPGS or should i not tune it because i have no gauges. Any help would be appreciated. THANK YOU I dont have the tuner on my truck right know its just at stock setting

 

nah, you would be alright imo

 

towing a 30ft camper with a predator tune installed is probably not the greatest idea without having gauges, the EGTS will get hot real fast if you lay into the throttle too much when towing something that big

 

the Diablo tuner should have a 40 hp setting that is made for towing. gauges are still recommended for anything over stock HP

whos gonna run wot up a hill

 

even stock the egts wont get that hot

 

i have seen an LB7 hit 1600*f when towing a 26' travel trailer with a diablosport predator set on a 60hp tow tune

 

I like to run WOT up hills but I have been told I am nuts though.....

As for running gauges it never hurts to run on the safe side and use some gauges I have seen 1500 on the egt in my old dmax climbing a grade but i had a bit more done to it.
