An engine is just an air pump -- you've taken moderate care of the exhale, now its time for the inhale.
The Renegade intake will finally match up to let your factory heads use their full port potential.
Keep the cam intake @05 under 212 and the duration 112-114 so the ECM stays happy.....................and you'll be happy.
Oh, have you replaced/upgraded your fuel pump ?
All this assumes you have no vacuum leaks and your tune is good.

Define power? What are you looking to realistically get out of the motor or to the rear wheels with a stock ECM? There are improvements you can make, but with a stock ECM you are limited to the mods that can be done, but it will still run pretty good actually.
