Ok so is there way to reprogram the 2UZ-FE(V8) and 5VZ-FE(V6) you are right about the piggybacks they are band aids.
Also have you heard of Superchips for ford from the flip of a switch you can go from stock setting to a race setting.You can also upgrade it evert time you do any engine mods. I heard about this when I THOUGHT I was getting a Lightning(parents like to twist there words around).You should contact them to see if they are interested in making them for Toyota motors.
