Add a cat-back as the "exhaust" mod and you're right on target.
What you didn't do was increase the fuel at lower RPM, which gains throttle response / torque (and HP of course) and add ignition advance in the midrange (more torque again). Those would be the biggest areas of gain, though the upper RPM will benefit from the timing and fuel changes also.
If the battery dies or is disconnected, the program will not be lost.

Thanks for the reply! I just wanted to be sure I would see some nice gains, whether it is peak numbers and/or more power under the curve.
