2001 Saturn sc performance upgrade

First post here, I have a 01 SC1 for a daily driver. It is a slow dog, what cheap upgrades can I do to get some power. Whats the word on these chips they sell on ebay? Do they do anything?http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&rd=1&item=7979598006&category=33597
I don't want to dump much money into it as it is only a daily driver. As for my toy The 1ton blazer project. It is a whole different story.

they are crap, for $10 they sell you a 5 cent resistor from RadioShack. it takes place of the Intake Air Sensor, replacing the true value with a fix false value. what do you think is better a real reading or a fake reading? it doesn't even matter that much, 20HP from the IAT is bull, the IAT is not that large of a factior in the A/F formula, i would be surprized if you see a 3HP gain. i should dyno this thing and prove its a scam once and for all
