Warning that at least on a 2002 or newer (and most likely on 2000/2001), removing and replacing the ECU is a ROYAL pain in the ass. I've just removed one and it sucked...

Also, getting a computer upgrade is best done AFTER you have done the rest of your performance mods so that the computer can be programmed to best take advantage of them.
