Youll notice a slight difference man, but If possible see if you can get the stall you want. I dont know why someone would talk your dad out of a 3000 stall? See if you can go bigger cause 2200 isnt a big difference at all. I have a Trailblazer Stall and mine stalls to 2400ish and I def. want bigger but needed something to get by on as a broke college student

If you go to a 3000 stall though, see if you can get a tranny cooler installed, they are pretty cheap. I have the 40k unit and got mine for 45$.
