Can someone clairify
 

I want to get tunercat or lt1 edit.Do any of these programs monitor your car while your driving it.I have a trans problem and I need to see whats happening at WOT.

I don't think Tunercat is available for your OBD-II setup. And only the OBD-I version of LT1_Edit comes with bundled scan software (pcmcomm). The OBD-II version of LT1_Edit does not include scan capability. You need AutoTap, or one of the other OBD--II software or hardware systems.

FAST has the software ability to monitor while driving/running your car, etc. In fact it's pretty sweet, last night I ran the laptop tuning my friends VE table while underload when he was driving. He replaced his ODBI ECU with a FAST ECU and we have been tweaking it on the road. You can compare your BASE tables for everything while connected in open or closed loop mode. I don't have their website but it shouldn't be hard to locate.
