I own a 98 4x4 club cabDakota w/ a 318. I have already added a super chip, throttle body spacer, K&N Filter, and a40 series flow master muffler. Does anyone of anything else that I can do to add more power with litle $$.

 

underdrive pullies, 1.7 roller rockers, no matter what you do you're looking at $200+ to make any real power.

 

do a search, this topic has been covered many times

 

The throttle body spacer needs to come out. It is not providing any gains at all, in fact, it will provide hp/torque loss. It sounds cool, but not made for multi port fuel injected motors. Don't believe me? Do a search of this forum and you will find plenty of info about this subject.

 

I second that. Sell it to some poor sap on ebayand use the money towards another mod. There's lot's of cheap and free mods, like adjusting your TPS sensor, orrelocating your IAT sensor. But like stated, to get any real gains, your gonna need to shell out a little cash. For your next mods consider maybe swapping out your mechanical fan for a set of electric fans, some headers, an aftermarket or moddedintake manifold, larger throttlebody, Mopar PCM or a flash. Then you can move onto more serious mods if you want like performance heads, cams, forged pistons, ect.
