How far can you go.......
before you need to rebuild a 4r100 transmission to a higher performance level due to engine or tuner mods?
Truck is a 2000 7.3 with just over 100K and totally stock.
I would like to at least do a turbo back 4" exhaust, new turbo wheel, and possibly a DP tuner. The concern obviously comes into play with the tuner in place. I am NOT looking for a drag truck, but for sure would like the truck to get out of its own way. I also would not like my trans to grenade and cost me $4K.
