Which water meth?
 

I've been looking at the Snow kits and trying to figure out which is best for me. I have an 2006. Basically stock other than and airdog and edge box of course exhaust and intake. 111k on the meter. We tow a 30' camper and other than that it's my daily. I want to run water meth to keep egts down and add a little bit more power. I had a super duty and ran one, but I towed quite a bit at the time. What's the thoughts? Spend my money else where? Thanks in advance.

those kits can flood in your cylinder and casue a rod to bend. so if you do install one, i would put some sort of a manual shut off valve in it. what are you seeing for EGTs? i would spend the money else where.

Forgot to mention that edge runs hot. So get rid of the edge and get EFI live. EFI is the best tuning you can get for a 2006+ truck, provided you use a good reputable tuner. That's where your money should go.
