3800 stall on a 3600 tune?

When i was putting the car together i sent my pcm to frost for
a stall tune for a 3600 but went with a 3800. Now am i leaving
performance on the table or should i expect my trans to go out?
Is 200 rpm really a difference? Ive only put about 100 miles on
It since installed.

It should be fine, the difference is so minimal. However, still check with the tuner just ask him

Well, I went from a stock stall to a 3000 on the factory tune, then recently put in an FLT lv4 with an SS3600 stall. Trans is still running the factory tune, but I did adjust the shift points with my Predator. N/A it was fine, but it would tap the rev limiter on the 2-3 shift when using nitrous.

I would think it will be close enough. You will know if it needs a tweak, hitting rev limiters on a shift.

No doesnt hit the rev limiter if anything since the stall if feels like it idles a bit lower in gear
Like if im pulling out ftom the driveway give it gas then let go of it quick it stumbles.

Thats normal. The stall is smaller in size / weight, so has a bit less inertia to keep the ole' engine spinning during instances like you describe.
