Theres alot of chip talk going on , Which chips actually work?????

[Hammer]

ALL chips (the hardware) should work fine. Any chip, no matter what the make, can access and the same settings within your car's computer.

The difference is the tune. Most chips are burned with a "default" set of parameters, or tune. Many shops may download different setups from Diablo. (Cold Air Kit, 3.73 gears, blower)

But even then, they are "generic" setups. For any chip to be worth it's cost, it needs to be dyno-tuned. Done right, you'll notice the difference. Done wrong... you could have issues.
