Just got done last night installing the Airdog. Took a few hours(about 3) from start to finish. Not hard at all, just time consuming. This is the 100gph unit.
Only been driving it for a day, but overall impression so far are great. The unit is not loud at all. You have to lean down kinda under the truck to hear it.

My truck is a pretty smooth running 7.3, but in the 50 miles or so i have driven with the airdog, the best way i can desribe it is that when cruising, accelerating etc. in a chipped setting, The injector noise resembles and is as quiet as when in stock setting or very very close. Just consistently smoother at speed. Throttle response seems a little better or once again more consistent. Its like driving around with good diesel fuel all the time, which was the point.

I filled my tank up and will report back/update this thread once i run it out and see if there are any MPG improvements.

Just figured i would give an opinion for others interested.

I am just buidling the foundation for the Terminator Twin HPOP, gtp38r, up pipes, regulated return with fuel bowl delete, etc i have laying in my basement Only need injectors which i will get in the spring and all will go on.



Oh and i would like to thank Clay at RiffRaff for the great price and fast shipping as usual.
