Lock-up is determined by the program and throttle %, not the converter. JFYI.

1) you dont need to lock up teh convertor
2) it maybe able to handle it but it isnt good
3) as above said its based on programing or a manual lockup switch
4) i wouldnt lock up under 105 mph or 5500 rpms

I will be trying it when my new FRC gets here this week. I talked with John and figure the next step up in TC is more for me And will wait til top end of the track before locking.

no i meant cruising, sorry to be ambiguous, so the stall itself doesnt lock up but the pcm program for our tranny determines it? i am all for getting good gas milage, trying to keep mother earth green by keeping my wallet full of green

oh that is just the programing. if you are stock it will lock up at the stock mph. go to your tuner for more info.

stock lock up is usually 40mph under lite load/cruising.. It will unlock around 37mph. Didnt notice what tp caused it to unlock.

Mine is exactly the same - and won't lock until the temp gauge reads just above the first mark (140 on the scanner if I remember correctly).

well if i switch to say, a 3600 2.4str fuddle converter, will the stock setting lock up at the same speed? i mean besides this and nitrous, im only going to have a lid, cutout, 160*tstat...

it doesnt change the lock up speed, only way would be with tuning or if you changed your rear gears and didnt reprogram the pcm.

You may experience a little "shutter" unless the entire TCC and effecting parameters are tuned right. I have a 3800 Fuddle, and not a real guru of TCC tuning. I have altered the mph for Apply/Release of the TCC, but at the threshold (a fews either side of Apply) when its locked it will kind ofshutter as if lugging a M6 in too high a gear and you hear and feel the drivetrain backlash. I have heard that adjusting the PWM in the trans settings will defeat that, wiating for an answer.
Depending on your gears and how tight/loose your particular TC is, you may experience the same issues using the stock settings.
