Modded auto experienced drivers chime in
This post is for readers that have modified their auto vette. Is this your experience.
This is what I have
vvt2 cam
Ported head
Circle d mod converter
F1A procharger
Arh 1 7/8 full no cats
B@b tail
Methanol
Catch can
Hopefully builders will chime in as well.
Here is what I would like to know.
1 .Was a modded converter necessary for that trans?
2. How does one know if there is too much stall?
Here is what it is doing. It appears it takes to many rpm to get get started and go through the first 3-4 gears.
Engine sounds loud at takeoff then gets mild through 3-4 gears until lock up occurs. Then loud again. Sounds like it is being switched from mild to loud.
Maybe I am being overly concerned. What do you think?

Sounds like to high of stall for the street for sure. I put money on it that your MPG has dropped in half. Plus sounds like problems in the tune. On a street car with a cam wouldn't want to drive a auto car on the street with much over a 3200 stall in it.
I had a F1X blower on the c5 with a 3200 stall putting down almost 1200 to the rear. But it still didn't act like what you are saying on the stall here.
Like above was said again these transmission are totally a diff beast here. If your tuners has not gotten it down on pressure on the lines, with shift points to the car's RPM. It will are should do and act like you are saying here.
