OK,my C4 is coming out to be freshened up and a tranny break put in and I've decided to buy a better converter,nothing wrong with it,but its a 2400 stall and thats to small.My question is what company makes a good converter and what size stall should it be?If this helps,I drive the car every day and attend Sat.night track events soit's got to be pretty streetable but good at the track.Any comments or opinions would be helpfull.Thanks Bryan
