Have any of you had ANY luck with any of the below "type" products? One claims to be LIKE a chip or flash the other is the every popular tornado ripoff.
I know they dont do what they claim, but do they do ANYTHING?
Even 1hp or 1mpg?
E.g: See examples Below,

P.S Car changed, now drive all stock '04 GT 40th Ann.
If no, What are some of the cheaper add on's you have done and see "for the buck" results?

It actually can hurt performance. Sorry you have to pay for performance. My best mod has been O/R H pipe with "cat back" exhaust system.
