Has anybody tried the GForce Performance Chip? If so what where you results with MPG and performance. Were there any problems after installing?

Do some googling. Looks like a lot of people think it's a scam.

I have done some performance mods on my past Grand Prixs but I don't think we can do a whole lot with these besides some custom tuning maybe? Cold air intake too.

Modern cars are not chipped. They are Tuned. The onboard controller is reprogrammed.
