i have a 01 psd and i have bigger injectors and swamps tuning, i talked to the guy where i get my tuning to see if i could get bigger tuning and he asked if i had a fass on, which i dont, i was just cerious is it really worth it cause he was saying i would have to still run the factory lift pump or maybe even 2 lift pumps with a lower fass, right now i am running 65psi and if i get on it it will only go down to 60 or little less than that. another question i got is what is the fass compared to the air dog or even the cpr ?
