performance pcm's or computers?

does anyone know if they offer any type of aftermarket pcm or computer that can be bought for a 96 cav w/ a 2.4? all I've found was a power module that affects the fuel curve and and timing. i need something can take all my modifications into affect w/o throwing off readings. Or if anyone knows where i can get my stock pcm reprogrammed with these changes, let me know. thanks

well you're SOL on that one. There's nothing out there that is a proven performer. Stick w/ the stock pcm, and get an air/fuel controller such as the one from Apex.
