can someone answer this.

Yes, most do. Although some are just scams.
none i have found and no way on the mileage change
Don't fall into those lies. Performance chips don't work. All they do is fool the car into thinking it needs more fuel and forces it to chug gas.
These chips are called a "Chipset", A chipset is usually designed to work with a specific family of microprocessors. Because it controls communications between the processor and external devices, the chipset plays a crucial role in determining system performance
YES, they do. Depending on what your trying for. my truck gets about 6-8 mpg more,(if you dont floor it all the time)
you buy chips and pay the person for the chips
Yes, They normally adjust timing and air/fuel ( like in the old days recurving distributor and rejetting the carb). They also can remove speed limiters, raise redline/fuel cut-off, and adjust boost on some vehicles.
where can I go to get my keyless FOB for my 2006 Grand Prix working?
Yes, Mod chips can help. But read the instructions carefully and do exactly as they tell you to. Also consider that if your car is under warranty, using Mod chips normally void the warranty. Check your insurance policy too. Increasing the performance of the vehicle without the companies knowledge might void the insurance as well.
yes they have improved performance in many horses and increase bounciness of the surface!!
yes the American battle chips do work on the Japanese progress pet. I have the enzan version and they work fine.
