I have a 06 stock C5500 motor home with a maxed out GVW it runs and drives great. is anyone running this tuner? I like the fact you can monitor so may things at a glance thats nice but will I save fuel and get more power when I need it like hills and pulling, without risking messing up anything?

If all you're looking for is added mileage and power, the Bully Dog will do that. It's not my favorite, but it will definitely do what you need. Let me know if we can help you out with one. http://www.alligatorperformance.com/product_info.php?products_id=3746

if you just wanna run a small tune you dont need all the gauges and stuff, just go with the plain tuner

I've been running the Bully Dog PMT, its great! I wanted the added EGT gauge and others so I went this route, really woke the truck up and I love the added monitoring abilities.
