I'll have to make a little video to prove it all, since I doubt anyone will believe me now. I guess I'll try a different method of testing the speed, but the last was pretty good, and the chassis is visibly slow.

Dan,
There are several threads discussing using a voltmeter on the output of the controllers. Don't believe them. The true indicator is the LED on the controller. If it isn't at full red or full green then you are not at full output. Both motors are connected and wired to run in the same direction? Are you sure of your wiring? Four Chalupas in trouble are going to draw a lot of current and therefore voltage drop in the wiring. Do the robot wheels turn faster when you lift the robot off the floor? Might be some misalignment in the wheel bearings. Try raising the robot and bypassing the speed controller, running breaker out to motor direct. Do they spin faster?
