Easy to download from the disc and update the Programmer for my vehicle. So far with the first tank of gas the mileage has improved about 1.5miles per gal. Runs smoother. Don't know about how it will do with my camper yet but will soon find out in a few weeks.

Got this for my 2003 Duramax and am well pleased. Haven't really played with it yet, but had one in an 05 F250 that was scary when turned all the way up. Usually use stage 2 for everything, but do kick it up to Stage 3 when on a trip on the interstate.. Stage 3 is too much for around town every day driving.
