Well I havent see many post about these things or I'm looking in the wrong area. But figured after hrs of research decided first I'd install a Banks Ram air filter set up. WOW what a difference!!!! Didn't really think the seat of my pants I'd notice or really feel a difference but Heck yeah!!! performance is a deffinate improvement. Installed it last night without telling the wife it made a difference her coming out of a Dogde Charger with a Hemi she's liking the Cummings disel. But after her 25 min commute this am she was amazed by the difference. Then tonight I installed the Boost fooler bought from the DTR store. once again added performce is very noticable. installation of air filter was 20 min, Boost fooler 30 sec's . It will be very easy if I need to remove it for any warranty work its truely a plug and play set up. I'll moitor the MPG's in the next few weeks and re post that info ,But if you looking at a non traceable upgrade thats really not to much $$$ boost fooler the way to go.
