i was curious if any one knows where to find a ecm that can be reprogrammed for the 4.0 or where to find the software to program the stock ecm. i did the 4.6 kit along with some other stuff and it seems to have a few kinks on start up and about 3/4 throttle. i want to run it on a local chassis dyno and be able to tweek the maps around a little.

Did you change out the injectors for some larger units?

yes

the site i was looking at recomended 24lb/hr injectors and i put in 26lb/hr injectors, i shootin for closer to 300hp at the wheels, we did alot of port work in the head and matching the ports on the intake and exhuast, bigger valves and springs, roller rockers. i'm also using a bigger throttle body with the edge module. the wrangler is a 99.
