more low end power

has anybody figured out how to get more low end power out of the vortec 4200 motor.

Find somebody that can tune the PCM to get rid of the torque management...

So what's the deal with the torque management?

programming in the pcm that saves a lot of wear on driveline parts (tranny/rearend). it basically prevents full power from being exerted immediately.

You can always launch in low or 1st, you are allowed more torque and power, not full potential but more nonetheless!

Any suggestions where one could get this done in the DFW, TX area? Or... does anyone sell a chip that accomplishes this? (I know Jet has a chip for the 4.2L, but I do not believe it disables the torque management, just changes shift points, spark and fuel?). Any help would be appreciated!
