You need the tune adjusted for the stall. Misfire code and a couple transmission codes need turned off with 9.5" high stall converters. 10" lower stall converters won't cause the non lock-up issue. My FTI did the same thing...I fixed mine by buying HPtuners, lots of googling, and learning how to tune.
Was yours locking up and then randomly quit? Thats the only reason I dont want to blame the tune, it was fine, now its not lol. But I would be very happy if thats all it was.
I chose my "small cam" based on the fact I should be fine with mail order tunes.

Trilk, it is very possible the tune needs to be addressed. If you're using HPT there is usually a user or 2 that will chime in that has the correct software to view/verify your tune is right if you post it.
IF(big if) you did by some chance wipe out the lock up clutch, you're pan/filter should be riddled with clutch material. Something that is worth checking for sure. I would start by checking that and see if you can get a 3rd party to verify the tune.

PS: you should also be able to see lock-up being commanded in your logs

Is there a benefit going with a multi disc in this setup for the street? What made you opt for him to go with the single?
Also since this is a street car is the converter locking up at a determined mph? I've read so much different opinions on locking up the converter on the dyno will destroy it in a hurry and also some saying this is what you should do.

Converter lock up happens at ~42mph stock, this can be adjusted. Some raise to 55mph, not sure the benefits other than I hate giving it half throttle at 35-40 then it locks up. I have heard something about locking up triple disc converters and lower speeds, not sure if thats a real thing though. To be honest id rather have it that way than have it lock up at 55 since I like to roll into it and dont do much WOT on the street.
I havent driven the car again, waiting on an IAC to show up. Hoping it cures my surge issue, if it doesnt, I am going to have to bite the bullet and get it dyno tuned and that will hopefully fix the lock-up issue as well.

WHEN you lock up is solely controlled by the tune and what you tuner likes to do. That all comes down to desired drive-ability, tuning, and the inputs it uses to decide when to lock up.(speed, throttle input, temps, are some of PIDs used to control lock up) So if you roll into the throttle or stab off in it after a certain throttle % its should unlock or not try to lock. And under a certain speed, it should unlock or not try to lock, and the same goes for temperature.

So I'm curious why someone WOULDN'T go with a triple disc over a single. Why wouldn't you want to lock it under WOT to gain MPH (performance)? The difference I believe is like $200-300. If I can pick up enough performance in the 1/4 to gain a couple MPH why wouldn't I want to go that route? Sorry, trying to learn here.

Alot of guys won't use the lockup down track even if it is availible
Most guys I know that decide to use it do sp because of a unique set of circumstances
-a gear/tire ratio that launches well and 660's well but runs out of rpm up top...they use lockup to get 300 more useable rpm instead of making a shift to 4th gear
-heavy cars that have to gear their car more aggressively to get moving and typically use a converter that works harder down low then might be loose up top. Locking cures the "looseness"
-Stock Bottom End guys that use it to keep from having too much of an rpm drop between shifts. Huge shift extensions can draw the motor down which is really hard on stock rods. So they get an extra loose converter to get really rollin and make it into the upper rpm in 3rd gear, then use lockup to get it to move out the back door without pulling the motor down too hard.
I've actually seen guys that lock the converter at the inopportune moment and slow down compared to unlocked pass.
triple disc isn't a one size fits all applications type deal.
So...all that mentioned above...plus 300 bucks...plus the extra weight...can easily lead guys to not go with a triple

Well I have a dyno appointment on the 28th. Should give me ample time to get my trans cooler installed.
The new iac helped, still surges in reverse. Was going to pay $125 plus shipping for a mail order retune and found a dyno here for $550. Sucks because the one literally a mile from my house wants $700. But he did agree mail order is a waste of money. At least I'll know it's right now!

Ok so the tuner said when he commands the converter to lock it doesn't hold. He said "Previous tune had minimum duty cycle as low as 10% which won't lock a 9.5" clutch". I assume he messed with it but he couldn't get it to lock. This was a dyno tune shop not mail order.
So that's just great, thing was annoying as **** driving down the highway with no lock up and 3.73s, and it's more uphill on the way home.
I don't know what to do next. Don't have the motivation for this.
