Got my truck back from the shop today with the full fass 95 system installed on it. My old lift pump was dead, now at idle I am reading 16 pounds and cant bring it below 13 at wot. Just curious as to the change in mpg`s now, got the air seperation so should do better. I know I have more power left about a 40ft. tire mark leaving the shop, OOPS!! ha ha. Only had my truck back a few hours but already like this fass system.

 

I installed mine and got 4 miles per gallon better on the fuel milage estimator thing on the roof. Noticeds way better power too.

 

ya i noticed a tiny bit of mpg gain with mine but mostly noticed how much smoother it ran

 

runs smoother with more power and a little better MPG. What could be better than that?
