The blue superchips were a standard tune that was given to all vehicals of that model. Normally they caused problems with the cars they were installed in. The red SCT chips are the newer versions that superchips sells. The only way to get a good tune out of a chip is to go to a dyno and have a tuner tune the chip for your car. Mail order tunes can come close but usually they aren't perfect.
