I have only heard bad about the ebay chips. I am sorry but there is a difference between even the high priced chips. Yes they all do basically the same thing, but they also all claim different hp and torque gains. I have the conforti chip from turnermotorsport.com and recommend it highly. I think it is one thing to buy mods for cosmetics of our car from ebay and have no problems buying taillights, shiftknobs, and such. Modding the engine with cheap ebay stuff on the other hand is something I don't trust and would never do.
Edit: Also when you order a chip you have to know the exact ECU number and production date of your car so that they can get you the right chip. Ebay doesn't give you that option. Who knows if the chip will work for sure.
