The manufacturer of the chip has nothing to do with the performance and power it makes. It has to do with the tuner, his abilities, and knowledge, and the car or truck he is working with. Everyone has their tuner preference and is entitled to their own opinion, but just remember, you get what you pay for.:tu:

By the way, I do agree with the mail order chips...they're crap. A good dynotune is the only way to go. Good luck with the tuner of your choice.
