More 6 Speed suggestions?

[jtbowen31]

I have been looking into getting a chip for my truck, which is a 1999.5 7.3psd with a 6 speed. So far it just has an intake, exhaust, and gauges. My biggest questions are with the higher horsepower tunes. I though I read somewhere on this forum that race tunes have more low rpm fueling than performance tunes, so would I be better off with the 100 Performance compared to the 100 Race if I want to keep the smoke down some? And for the last position, will it hurt anything in my truck (besides the clutch-plan on upgrading it soon anyways) to run the 140 hp tune, would the 120 be better, or should I stay away from 120 and 140 all together? I am pretty sure I have forged rods, but I don't know enough about these trucks yet to know if there are other things I should look out for, or if there are other supporting mods that I need to get done. So I guess right now I am looking at:
1- Stock
2- High Idle
3- 65 Tow
4- 80 DD
5- 100 Perf or Race
6- 120 Race or 140 Extreme
The truck is mainly used as a daily driver and as an over all fun vehicle. It rarely has a trailer behind it, it doesn't sled pull, and it isn't the most practical to drag race with.
Thanks in advance, and any other advice or suggestions are welcome!
