Advantages/Disadvantage of stall
When you floor it, instead of ******* its way up the powerband (slowly increasing rpms), it will flash it to 3k rpms (or whatever your stall is set at). It is similar to dumping the clutch in a 6-speed car.
Secondly, when you are driving certain MPH (40 and 70 for me), when you floor it you will hit dead spots. The gear will not drop down and you will slowly pull through 2k, 3k, 4k rpms and so on. With the stall, when you floor it, there will be no dead spot. It will flash up to your stall speed.
Having a stall puts your car into its peak power spots much quicker. You will drop about a second in the quarter mile with a 3500 stall and sticky tires.
On stock/bolt on cars 3-3500 is a good stall. I would not go less than 3000 though.
If you add a medium sized cam, 3800-4000 is a good point. A huge cam would benefit from 4400+ sized stalls.
Most people don't experience bad gas mileage as a direct result from the stall. However, you may find yourself hot rodding a bit more!

as i understand it, any aftermarket converter will heat the tranny, requiring a cooler.
I've seen some complaints/issues with fuddle lately.
Precision Industres (Vigilante) is pretty much the best in the business. I love mine.
Yank is also highly recommended
