I got my edge before they came out with the hot juice app. so mine is 100 hp on level 4 and 115 hp on 5 and i've never had any problems when i do what it says and drive the truck for 200 miles to get the tranny used to the new hp levels......if you run them on level 3 (80 hp for me) and bump it up to 5 and go race someone then your askin for trouble....
all in all i don't see why running it on 100 hp whould be a problem and for me there is not much difference between 100 hp and 115 hp (levels 4 & 5)
mine was also "pre-hot code" so level 5 was already whoop ass level, but was definitely more than 115 hp
