Stall locking up at wot at 100mph? Feels like a shift? Every now and than when I stomp it going WOT at 100 mph the rpm's drop from 5k to about 4800 rpm's, it feels like a mini shift. I am thinking it is the stall locking up for some reason, but just wanting to know for sure what it is. Any ideas?

The problem is only at WOT. My car normally locks up at normal acceleration at about 45mph. I just changed the fluid a cuple thousand miles back when I put the converter in. It has something to do with the new stall or something.

Sounds like a third gear problem.
If you have a 3.23 rear and stock size tires it should be at approx 4600 rpm at 100 mph in 3rd. It sounds like it's sliding into third gear.
It could be a million things, even engine fueling.
Theres not any chance you still have torque management is there?

Here tell me what you think of this. Here is our email conversation.
Me- Hey Bryan you did my retune a cuple months ago. I got it retuned because I got the new circle d 3400 stall. I have a question. When I stomp it WOT every now and than at 100mph the rpms drop from 5000 to 4800. It feels like a little shift. Could this be where the wot lockup is set on my tune? Any ideas?
Bryan@pcmforless.comm says- Yes, that is the WOT lockup MPH, it helps you get a bit extra MPH in your 1/4 mile time.
thanks,
Bryan

Did Circle D build the converter to lock up at WOT? Chris told me that my 3C should not be allowed to drop 1000 rpm during normal cruise. That means don't let it lock up at WOT.

You might want to check with circle d on the wot lock up, not recommended with your converter from what they told me. I see you have a single disc 2C https://ls1tech.com/forums/automatic...e-d-today.html
Anyway, depending on your rear gear and tire size, heres the math:
Unlocked 3.23 x 355 x 100 / 24.91 = 4603 rpm
Locked l 3.23 x 336 x 100 / 24.91 = 4356 rpm
Thats a 247 rpm difference.

I don't get it. You say you have a problem that feels like the converter locking or something and you know it is the converter locking.

I don't know, ask Circle D if it's ok. One or two mph is not worth beating up the converter IMO. But on the other hand a 200 to 300 rpm drop doesn't seem like much, even at WOT.

How fast will it take out the clutch? How much time do I have to get it retuned? I was planing on taking it to the track this friday. Should I not?
