Ebay mod chips

[audiodude332001]

hey,i was just looking around on ebay and I found this "High Performance Intake Timing Mod Resistor" that claims to add 15-20 hp.Is this BS, or do these actually work? Here's the link: http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=2425675891&category=33597
