Didn't they post some numbers in the one post about tuning an Auto C6? I tried finding the thread but couldn't find it. The search function didn't seem to be too helpful either as it didn't even find this thread when I put in LPE or Lingenfelter!

crank vs rwhp
with manuals it's about 15% loss, with autos it's about 20% loss. If you're making 500 crank hp, you rear wheel HP is 425HP.
to calculate: RWHP or TQ divided by .85= crank or flywheel HP or
flywheel HP X .85 = RWHP or TQ
