Has anyone completely removed their TM?

Hmmm...very good info. Seems like I've repeatedly heard that TM is the main offender in the factory de-tuning, but it appears that isn't the case. Can someone list the different types of TM, and how they work...how about abuse mode? What triggers that and what does the PCM do when in abuse mode?

Here are most of the applicable tables from EFILive. Not sure why Engine> Torque Limiting would have limits for front and rear axles when 4X4 trucks do not have traction control (note that EFILive says this table is used with traction control). Therefore, I have disabled all limiting here in my calibration just in case it is used by the PCM somewhere along the line.
There are Abuse tables in both the engine and trans sections. There could be other triggers for abuse mode that we do not have access to, so I just disable it altogether.
The Brake Torque Management notes are self-explanatory.
Shift Torque Reduction is what I said may be only momentary.
Torque reduction can be achieved through spark reduction and/or closing the throttle in electronic throttle vehicles.

Ok this is good info but what about guys with Nelson tunes and such? I know you can reduce TM but what about TCS and abuse mode? My buddy had a built 87 rcsb automatic and when you hit the accelerator there's hardly any delay. I'm trying to obtain the same feel that you get with a manual trans vehicle, instant accel. All this TM, TCS and Abuse garbage is annoying to me. I feel the delay in my truck and I want it gone.

yeah my 5.0 put instant power down. maybe I'm just asking for too much, after all it is a truck. I wonder how much it would cost to get my truck to where I could roast the tires from a 20-30mph roll.
