personally the way i see it is even if it doesnt give you gobs of power its still going to help. when you seperate the air/fumes from the fuel you get clean pure fuel which is always better for your power plant

got my airdog 150 on the way in the mail today! pumped up to see if its going to add anything to my truck but if i doesnt i still know it will next year when its time for the twin turbos! :U:

On both of these systems does the draw straw have to be changed on both systems

Depends on which one you get. I believe with both the FASS 150 and Airdog 150 you have to drop the tank. With the 100 of each you dont have to drop the tank.

I personally would go for the 150 and drop the tank or raise the bed - its really not that big of a job.

I just put the FASS platinum on and even with dropping the tank only took us 2 1/2 hrs to install. Its very quiet compared to my buddies airdog and i noticed a little better gain in low end and also gained about 1-1.5 mpg. I really like it so far no complaints and i debated for a long time over airdog or fass.

I just put a Air Dog 150 on mine and as skinnysfd has said I gained on the bottom end as well and my mpgs went up as well I am very pleased with the ease of install on it. And too it only took me about the same 2.5hrs in my gravel drive way by myself and that is lifting the bed. I would recommend these systems to those who are looking. I just put a quad adrenaline in last week and the fuel press holds steady and does not drop at all. :rocking: :choochoo:

Great info! Thank you so much. :tu:
