Performance Chips on Ebay

Any one have a take on these stage I,II, & III performance kits. Ive heard a lot of dissatisfaction with these but these stage kits are new too me. Heres the site: http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&category=42604&item=7942186151&rd=1

20whp LMFAO!

its a 20cent resistor at radio shack that "fools" the computer.

it looks like a stage one is crap, its just a risiser as sk8er said, i got one once and it screwed up my car, i have an auto cavalier and it messed up the shifting it shifted so hard the car was lurching and stuff, i dont kno about a stage 2 or stage 3 if someone does let me kno too, cause it sounds good but like i said i dont kno about those cause all ive tried was a stage 1

waste of money and a stupid question to ask... None of these chips actually serve a purpose except dumping more fuel into the cylanders causing you to run rich...

If it sounds to good to be true, it is.

thanks for the info guys
