I swapped from 3.42 to 3.73 and didnt not program any thing was done at RPM trans, but i'm a manual not sure if that matters? speedometer is dead on checked with gps
before i committed to the swap I ask they guys and they said it reads on a wheel sensor I think it was and no programing is needed

One person recommended that I not upgrade the gears unless I was planning to track the car a lot. He said it wouldn't drive as well on the street or highway. I would love to hear your opinion on that after you've had it for a little while!

Not when you send the PCM in for our $149 mail in tune special. PCM's usually turned around the same day.
Oh and yes you must tune the car when switching gears in an auto. Well if you want it to drive correctly anyway.
