I have a SS3800 and around town, keeping up with traffic, mine will slip to around 2500 RPMs. I have come to understand, I may actually have a 4000, not a 3800. I don' t really have a problem with that, but, I always felt my shift extension was always pretty high. anyhow, if you want a tighter converter, look into getting one with a lower stall.

 

A heavier car will make the converter slip more.

 

A 3200 stall in general will feel relatively tight. I have a TCI 3500 and I think it feels tight. I move ok from a stop. If I'm on level ground I will creep forward on idle. Light throttle reacts slower then before but not what I would call a night and day difference. The biggest difference I see is that reverse takes alot more gas then it used to

Yank SS series are known to feel tighter then other brands as well as being more efficient. A SS3200 should pretty much feel stock until you punch it. I would honestly consider the SS3600. They are one of Yanks most popular street/strip converters for the LS1 vehicles.
