I searched around but didn't find much.

I'm going to order a ss3600 stall and I already have a Bolton tune from frost. Would I need to send my PCM back for a retune? Or will I be ok?

 

You'd have to send it back for a retune to adjust the shift points and whatnot so you aren't bouncing off the rev limiter and can make better use of shift extension. If you got the tune within the last 90 days he will update it for free (just pay shipping).

Yank will also recommend a "break-in" period for their converters, somewhere between 150-300 miles of easy driving I believe so the internals can learn what to do.

 

Looks like im paying for a retune lol.

Aren't their some people with out tunes doing fine with bigger than stock stalls?

 

I'm one of those 'some people'.
originally I had 3.23s' with stock stall(1800)
then 3.23s' with TCI 2800
then 4.56s' with TCI 2800
then 4.56s' with Yank SS3600
now back to 3.23s' with Yank SS3600

only tune the car has seen is what came from factory,except for 4.56s' programming to correct speedometer. Shift points never changed and never hit the limiter.

gave good info, you can/may get by with out tune, but you sure need/benfit from one.
just my .02s Johnny

 

Retune. I was hesitant about a frost tune for my converter but it seems to be doing fine. I'm sure a dyno tune from a good tuner will be better tho.

I had a 3600 put in and ha to get it tuned it had a weird chattering around 35-40 it was the lockup engaging. I think it's safer to just get it tuned

 

vote for a tune here thats what i did

 

Tunes no problem I was just wanting to know so I can factor that into the cost.

 

As far as lock-up goes i dont see a way around a tune, i guess some people have luck but in my experience stalls dont like those factory pwm lock-up parameters.
