Thanks

Well I am almost ready to send the harness and ecu off but not sure what gear to run in the rearend the gears now are way to high (not sure exactly what they are but 1 3/4 turns of driveshaft is one rotation of the tire.) anybody runing a similar set up got any ideas I was thinking 3:55. Im running a 29" tire. I would like to have good power from dead stop but also wanting to get good fuel milage as that is the reason I decided to go with the 5.3 and 4l60e.

Also what rpm should I shoot for at highway speed 70mph not real sure were the 5.3 does the best.
