More or less a chip or tuner is about the same...BUT with a chip you can order different settings for it such as nitrous, blower, street, strip 1, strip 2, etc. With a tuner like the predator you're stuck with the default tune and if you want anything else you have to download them which after the price of the tuner and all the needed hardware comes out to be alot more than having the chip done. If I could do one thing over again it would be to go with a chip rather than a tuner.
