Are chips ripoffs?
 

I was browsing ebay for performance parts and I ran across these "chips" that claim to squeeze up to an extra 15 hp out of your engine. They're only like 30 bucks.

Here's an example of one: http://cgi.ebay.com/ebaymotors/ws/eB...AWNA%3AMT%3A12

I'm skeptical. Has anyone tried anything like this? Im curious to hear about your results.

I'm aware of changing the ECU or getting a piggy back, both of which can be quite costly, but also seem more likely to produce results.

That is a pot in a box that goes inline with the IAT sensor, 2.50$ worth of parts from an electronics shop, well 4.00$ if you add a project box i guess.

They're useless, don't waste your money on them, seriously. It's a resistor in a box.

Yeah, figured as much. Thanks for the input.

my brother in law bought one of those lol what a joke. it also said "increases you gas mileage" HA

Ya... dead give away. I think people in these forums would be more likely to believe an extra 200HP from mods than an extra 5mpg from mods.
