I have the airdog 100 on my truck and have had nothing but good luck with it. It's been on for a year now and ever since install, Ive never had to fix or readjust anything at all. Plus with the 100 kit you don't have to drop the tank and put in the draw tube, you use the factory connection. With all my mods I haven't seen a pressure under 14 psi at wide open throttle. It works very well in my opinion...

 

Both are good. I prefer Airdog because price is lower.

 

I ended up purchasing the AirDog 100 because it was cheaper then the FASS. It has been on the truck for almost a year and I have never had an issue.

I run a 4inch exhaust on my truck no chips or injectors and have the air dog 150. I have had it for almost 6months and have had no problems with it it actually increased my MPG's id recommend air dog.
