Hi everyone. Loving the site. I searched for "tcc lock wot" and read the following threads/pages.

It never even occurred to me to think about TCC lock at WOT until about 3 weeks ago when a guy brought me a GMC Sierra with a 416 stroker and a 3.9 Whipple for a tune. It is fond of the rev limiter. That led me to this site. I've been tuning EFI for a long time but only transmissions for about a year, and then only stock stuff (hey, we can't know everything, and I am learning more and more each day).
My very naive and new-guy question is simply, when should I be tuning cars/trucks to lock TCC at WOT?
1) Always?
2) At a certain point of power or "build level"?
3) What are the factors I should consider to determine if I should be making a tune to lock TCC at WOT?
4) Does weight of vehicle or HP level come into play here?
Is it safe to lock TCC on factory torque converter? Reason I ask is for my own truck. It is a 2014 Silverado 6L80 T43 with 24270599 operating system has a switch under transmission>torque converter>general>shift lock set to disable. I expect this means my truck will never lock TCC at WOT. I am always skeptical of switches like this in HP Tuners (my experience is that sometimes switches are liars).
1) Is this switch reliable?
2) Is it safe to play with TCC WOT lock on my Silverado?
3) It's a cam-swapped 5.3 with long tube headers and Edelbrock E-Force supercharger. Makes about 500 tire. Stock trans, stock stall.
4) Yea I know, try it and see. Just thought someone with more knowledge and experience may want to weigh in on this before I start breaking stuff.
Thanks everyone.
