Ok, let me help try to clear up a couple questions that have been raised.

Stock Stall:
The stock converter has a variable stall, as in the actuall stall can change depending on conditions. The materials used inside the factory converter allow it to stall out at different speeds. For the most part, it stalls anywhere between 1800 and 2100 RPM's. This allows for a very comfortable driving experience for the normal everyday drivers.

Higher Stall:
This converter has been designed to stall right at 2600 RPM's everytime. APC had to go through several testing phases and redesigns to get the converter to always stall right at the desired RPM. The results is clearly night and day between this and a factory converter. When you want to nail it, right on the mark as designed, it stalls out at 2600 RPM's. Being as consistant as this was designed is one reason the computer doesn't seem to have a problem with it. Most others who have made higher stall converters are experiencing problems with the computer systems. APC does have another one that they have been testing at 2800 RPM's. As far as we currently know, they have not been having any computer problems with this level, however this is borderline. Anything else higher than the 2800 seems to give the vehicle computer system hell, they don't play well together.

Size:
The APC converters are actually factory housings with reworked insides, so the size has no change. There are billet converters available as well, but these are also aproximately the same size as stock.
