I'm putting a 3500 stall in shortly. Should I have my shift points reprogrammed? If so, what should they be changed to?

Motor is stock. Car just has bolt ons.

 

I don't have a high stall but if I did I would let my butt be my guide.

Installing a looser converter should not impact your ideal shift points since it doesn't change your powerband.
Only thing you might have a problem with is the no 1-2 shift.

 

It will depend upon how loose the converter is. Sometimes the extra slip of a high stall can cause you to hit the rev limiter before the mph of the shift point. If it doesn't then you're OK.

 

That would require one loose converter!

 

i had a 4000 stall running great and without a problem and was pretty good as a daily driver. it was surprising how good it work after hours of tunning

 

Not that kind of loose I'm talking about efficiency at WOT in the upper rpm ranges.
Say that the stock converter is 95% efficient at 6000 rpm netting 42 mph. If an aftermarket converter was 90% efficient then 6000 rpm would only net 40 ish mph and you'd hit the rev limiter before it would shift.

Like I said: If you don't hit the limiter on shifts then you'll be fine without programming.
