Performance Chip Direct

Has anyone ever used a Performance Chip Direct chip? www.performancechipsdirect.com Just wondering if they are good or bad?

Thanks, Brian

That is pure garbage. Won't do crap and will probably cause a check engine light. All it is is a resistor in the IAT (Intake Air Temp) sensor that fools the computer into thinking the engine is cold. Don't waste the cash.

Well, I already bought one and am going to try it. Looks pretty decent. We will see if it performs like it looks. Yes I know it changes the signal to the computer, isn't that what all chips do? I will post the results...
