Is this for real?

CHEVROLET AVEO GF Peformance Chip

That would be awesome and well worth it, but would it really improve power and performance and mpg??? Sounds a little too good to be true... id really like some other peoples thoughts and recommendations.. I was also considering doing short ram air intake or putting a cold air intake setpu on my car to imrpove performance..but I'm not sure if the push would be worth the shove.
