I would like an opinion as to what to do first. exhaust, air intake, or programer?

I am trying for fuel milage and power too.

twalls,

Get gauges first, or the Edge Juice and Attitude that has the gauges, that way you are aware of what is going on etc. Then look at exhaust and intake followed by a HP module, again unless you decide on the Edge Juice and Attiude that has the HP and gauges combined. We will be glad to help you with questions just give us a call.
