I just got my car back together and running. I use tunercats and was looking for should I change shift points and/or tcc settings for new stall?

How is it shifting at the moment? does it feel okay? or a little "loose/weak" during shifts?

It is a good idea for changes to be made in the computer, but if you haven't really touched the trans settings before I wouldn't recommend doing it on your own.. unless someone here can tell you the adjustments that should be made (which is obviously what you're looking for haha)

when it shifts it shifts fine. I was just wondering if going from a stock stall to a 3500 what if anything needs to be changed.

I had to get a new email tune from madtuner when I installed my 3600 and my brother had to get one when he put in his 3400. Both 95 LT1 engines. We were having problems with lockup, not shift points.

How does it drive on the street? I have the same cam and I am shopping for a stall now and I don't want to go overboard and lose all streetability

Sorry didn't mean to steal your thread, just looking for some advice:secret:

In the ECM constants there is a Vss diagnostic Enable min RPM that should be raised to about 4000 rpm's. Sometimes with out raising this you will go into a limp mode while leaving the line hard. Some tunes that I've seen has had this raised higher while other people haven't had a problem with it. I've always raised this one higher then the stall
