Gear change reprogramming?

I have replaced my 2.73 gears with 3.42 gears. I now hit the rev-limiter before upshift. The PCM needs to be reprogrammed. Living here in Iowa " fly-over country " I do not know where to get this done. Any ideas?

any local speedshop that has tuning capability should be able to do it.

also, a Diablosport Predator handheld will make necessary changes.

Mail order tune or superchips tuner is the cheapest way. I bought a superchips for 149.00 at the bay and programed mine until i could find a dyno tune facility. If you buy a used handheld make sure it has been unlocked or it will not work on your car
