More for economy than power, although they sorta go together ;-)I highly rrecommend just doing a drop in air filter and sabm, not a cold air intake. Nothing against volant but me and my buddy @jbroas did a bunch of testing one day and found that a CAi doesn't make a truck any faster at the track.
A cold air intake and sabm can be done for less than $100. That leaves $$ left over for a BullyDog or hypertech. Both of which I've dyno tested and realized gains
Have to ask a stoopid question: sabm?
