does the nelson tune do everything that the superchips programmer does? i would like to change to get more out of my truck, if it's possible. any other feedback about other mod's that could help this daily driver would be appreciated.

for instance:

shift points
speed limiter
rev limiter
trans press.
trans firm
91 oct tune
adjust elec. fan's for 160* t stat


what could the power outputs be with the nelson tune on my truck, (see signature)
i see that the superchips has gotten 20 hp, 32 lbft.

thanks
