TC vs. Gearing
Which is a better mob for a non-track daily driver with an owner with a heavy foot: a TC or gearing? The truck is a stock '03 with 5.3l, 3.42's and a G80. As most of you know, it has a real good pull from say 2800 rpms to 5500 rpms. Gearing to 4.10s will get to the powerband quicker than the 3.42s, but the TC will get it there quicker to 2800 than the 4.10s. The truck does no towing and will see only limited long distance highway miles.
Does a TC of 3000 rpm stall require and PCM tune? I know the 4.10s will, but I have a handheld that can take care of that.

I will say the T/C also. I made a similar swap in my 04 a few months ago. I went from 3.42's to 3.90's. While it helped some, very little, it wasn't much. I will be installing my new T/C soon along with a shift kit and vette servo and removing the rest of the torque management. That should help quite a bit.

Gears and converters theoriticly accomplish the same thing.. they are both torque multipliers. However they do act differently. I feel a converter would be better for what you are wanting because it will not effect the rpm/mph range of you truck thus keeping you current stock feel when locked for highway trips and other daily driving. You also do not require any tunning with a converter where gears would. Personally, I think converters make automatics much more fun to drive.
