figured i would run this past you guys to get your opinions. currently i run a 6637 intake on the truck. i have stage 1 swamps sticks and an h2e. in my hottest tune i can get my egt gauge up to 1500 very quickly. my restriction gauge gets sucked all the way down to show "clogged" or "restricted" filter on the filter minder. i thought i read somewhere that the 6637 filter only flows 30% more than the stock setup. im kinda thinking that my filter is seriously restricting my airflow and top end performance. ive been looking at getting an afe stage 2 since its supposed to flow 200% over stock and alot of you guys run them and like them. what are your thoughts?
