TCC slip while driving?
TCC slip while driving? 
At WOT the converter should not be locked and the slip
depends on the engine torque, converter stall & STR,
and trans input shaft RPM. Given that, not much chance
of a crisp answer.
But me, I see maybe 500RPM at the big end; you'd like
to see (input shaft RPM)/(engine RPM) north of 90%
(I hit 95% on the Fuddle, and saw 97% off the TCI
3000 before). At lower RPM it will read worse, but the
true efficiency is better than the RPM/RPM ratio by
whatever torque multiplication you are netting.

Thanks Jimmy.
I see about 137% on WOT runs and was curious if this was normal. First time that i have logged this PID.
