The reason I didn't like the 3000 stall was because I had it in my 99 V6 and it was horrible! In overdrive on the freeway I had to be driving well over 80 MPH (65mph speed limit) to get it to stay locked and it was very annoying.
The only way to keep a high stall torque converter locked is to keep it at wide open throttle.
You NEVER want a stall that is higher then your crusing RPM or it will constantly be trying to go into neutral.
I can't remember off the top of my head (someone google it) but a stock AR70W trans is around 1100 stall.
My 2600 launches almost as hard as my 3000 stall did, but my driveability with 4:10 gears is almost a perfect match for quick launch and daily driver.
That's why I said, if you have a full on track car, go high stall, because when you drag race, you never let off the throttle.

i disagree i have a 2500 rpm converter and it doesn't feel any different than stock. a 3000 converter will be fine on the highway because of converter lockup in 3rd and 4th.
i drove a friends 99 v6 with a 3000 converter and i am real sorry i didn't go with a 3000 stall. it gets off the line nicely and has very good driving manners

I have a Trango shift kit, a torque converter and a Diablo Chip. I honestly think I could have achieved the same thing without the Shift kit.
edit: My T/C is a 2600rpm. I wouldn't recommend any higher rpm T/C unless your V6 is strickly a track car, because if it's a daily driver, it would be horrible on the hwy. But I will say I love my launch leaving a stop light. I don't know what my 60' is, but I can guarantee it's better then a V6 with a stock T/C.

the computer controls when lockup occurs not the converter or tranny in a properly running tranny and converter. at highway speeds like 60-70mph the computer senses when you are only at part throttle and locks the converter to save fuel. lockup is only accomplished at part throttle and will never occur at WOT unless you gradually gain speed and roll the throttle to WOT over a long stretch of road
my friends 99 with a 3000 stall drives just like a stock converter at highway speeds which is what it is supposed to do
i noticed no difference between my 2500 stall and stock which is really about 1700-2000 rpm stall stock

Your information is text book on the money except your missing one very important fact. It doesn't matter what you computer tells the trany, if you have a higher stall then your crusing speed (give or take 500 rpm) your trany will try to rest in neutral in overdrive, no buts about it. I don't know what your friend told you about his stall, but if you witnessed it personally on the freeway driving perfectly at a crusing speed, then he did not have a 3000 stall T/C or he had a COMPUSHIFT (which I've heard tale of) or something of that nature. When I had mine, there was no such animal for a AODE and 4R70W or none that I knew of.

it's a PI 9.5" single disc lockup stalled at my requested 3,000 rpm's when i ordered it. he has no compushift either. i have never seen 1 personally but they are supposed to work nicely
it drives just like a normal stock converter on the highway. he still has stock 3.27's too
if you modify your computer to lockup at WOT you need a multi disc converter
my 98 would go into lockup at 1000rpm's with the stock 2.73's at just above 45mph in OD which is well below the stall speed of the stock converter
when your computer senses a load more than the available power at hand while locked up can handle thenit unlocks it and may also drop 1 gear into 3rd non lockup and alot of time lockup quickly after dropping into 3rd nonlocking
my 2500 stall drives exactly like the stock converter. slow launches just like stock

My 2600 stall fully locks at 2600 rpm while driving and it's very easy to feel and hear. When I drive around town, I always turn off my overdrive and I drive high in the RPM range using my gearing to regulate where I keep my rpm.
Now from a stop, I can feel a "hard grab" at around 3000 rpm. When I leave a green light and when I stomp on the accelerator, I reach 3000 rpm VERY quickly and 3000 to 6000 rpm, I can feel the G's (as far as a V6 is conserned) and when I shift into second, I don't just get a little bark, I leave a double 3 foot patch of rubber on the street. Even with my possi and wide tires, it breaks loose a bit too much for my taste and I'm hoping traction bars will help with that problem, but I've been told that it won't help much in my case. I still haven't bought a trac bar yet because I may be doing something different to my rear end. I haven't tried drag radials yet either, but I've been told that they would be my best bet in my situation. I know D/R's are a lot of bux to spend on a daily driver, but the truth is, I've put less then 10K miles on my V6 since I bought it in 03 because I hardly drive it. So I might just do the trac bar and D/R's for ***** and giggles because I'm not 100% sold on the Kenny Brown rear end system I'm getting talked into, because it's REALLY expensive and designed for a race car. All I want is a street legal V6 Stang that is the closest thing to a race car without being illegal. California has very strict regulations.

Are "traction bars" the same as upper and lower control arms? I haven't seen any traction bars for any 1990+ Mustangs

I was thinking about the HPM Mega-Bite Jr. package because I've heard good things as far as trac bars go. Also Lakewood makes a good package.
