I also did away with the torque converter lockup in 3rd gear. I had to adjust the lockup because the new stall was not locking until about 60 mph when it was installed. It now locks up under light throttle at 45 mph, just like stock. I've found that shift speeds and lockup speeds tends to be a very personal preference item. I like to shift and lock up early under light throttle inputs as it tends to help with gas mileage. You have to play around some with your downshift mph parameters some to get the right balance.

I lock up as early as 35 mph under light throttle.

I thought I recognized a name over there.   

I've been happy with mine.  I noticed on another thread where someone was looking for a high stall converter someone dissing the TB converters due to issues at WOT with the converter locked.  To that I say, why would you have your computer programmed to keep the converter locked at WOT in the first place?  I'm programmed to only lock the converter in 4th, and I'd have to have the truck going faster than I've ever driven it (110) to have it hit 4th at WOT.  People shatter driveshafts on the 2wd AVs doing dyno runs in 3rd - the driveshaft is only good up to about 125.

Stock, the computer did lock up my converter in 3rd.  After putting in the TB converter, I found it a bit odd that when shifting from locked in 3rd to 4th unlocked, the rpms would increase as the converter was unlocked, then decrease with the shift.  Didn't see this with the tighter stock converter.  May have been there, just not very noticable.  Since I don't do long runs of driving at speeds where the tranny would be running locked in 3rd anyway, I just programmed it to only lock in 4th, and have been very happy with that.  Have had the TB converter in for I think 3 years now, roughly 90,000 miles.

Mine would try to lock at WOT until I adjusted the tune as well.  I say "tried" for a reason.  I shuttered like crazy trying to lock up at WOT behind a motor that was making at least twice the power as what it was made for.

Mine now will never lock at any speed or in any gear above 80% throttle.  (I think it's 80% but regardless, above a set tps %, it won't lock.)
