4L80E with a Speed Density Tune
Is anyone running this setup?
In the past from what I have seen with the Auto Transmissions when the MAF throws a code the PCM will command Max Line Pressure. Since running SD you trick the PCM by enabling that MAF Code on first scan, will this affect the commanded Pressure of the 4L80E?
Is there a way to get around this?

Mike13 above meant to set the DTCs to not-reported in the transmission diagnostics tables (DTC Max Pressure, DTC Fault Pressure, DTC Failsafe Enabler)
[ leave the engine MAF DTC enabed, otherwise you won't be running in SD ]
