Ok now I have my chip reburn along with baby swamps and wicked wheel, needless to say the truck is a beast, boost needle goes straight to 30lbs the filter minder pegs out totally, I already have a 6637 filter is there a better setup that still uses a paper filter? I am very suspicious of reusable filters but maybe some are ok, I've seen very bad oil sample results from k&n filters.

6637 is the best one. Don’t let anyone tell you and difference. A member here dynoed countless of times and 6637 came out on top. Forgot the post/thread.

Look up the blue 6637, it’s what I use in the intake kits I sell for the idit trucks.

Alright, I have a blue 6637 on the way, I also have a donaldson powercore filter coming too that basically has the same dimensions as a 6637.

So I got my 40lb boost gauge today and on light tow/daily I'm hitting 34lbs, I was too chicken to see what it would be on the two higher settings.
