I have often thought that if we had access to all of the EGR parameters that we might be able to use the EGR circuit to control TCC. That may be a goofy thought but, it won't go away.

98 GMC RCSB, 5.0, 4L80e, Moser M60, 4.10 gear, Homemade twin turbo w/Junkyard T3 turbos, 24x CNP, 12200411 PCM.
I sent the information below in a PM. Hopefully, when others find this tread in the future, the information below will help.

Likely the only way an '0411 would be able to control a 700R4 TCC is in 4th gear only.
The TCC information below is from the "Internet"

"Set the TCC duty cycle max table to 100 & the TCC duty cycle min table to 90. This is to eliminate the TCC slip, nothing to do with rpm oscillation. You may have to raise the TCC lock up speed. With a cam like your's, there will be low rpm light throttle surge. Tuning will help, but will not completely eliminate low rpm surging/bucking."

"From the factory the PCM pulses the pressure solenoid for the torque converter lockup to maintain slip and engage smoothly. To disable it you simply set the entire max table to 100% and the entire min table to 99%. This will make the torque converter act like an on/off switch which is disabling the PWM."

"You should set the entire "PWM" table Min to 98 and the Max to 100%"
