Auction is for the eprom chip only, you will have to either install the chip yourself or take it to a TV repair place and get them to solder in a 28 pin socket in place of your original chip, this takes less than 30 min for a pro and should cost you less than $40.00 to get it done professionally.

Chip will be packed securely and safely, they are delicate things after all...


Why chip your car ?

The manufacturer has to take into account many variables and emission standards when mapping the chips, as such there are many compromises made. 

We do not compromise with the programming...

A quick note: installing any performance mod to your car, can amplify an existing problem with your engine, most commonly in the ignition system with old coils/coil packs, sparkplugs (incorrect or maladjusted), leaking leads, O2 sensors and Airflow sensors being the main culprits.
All our products were tested on vehicles in excellent mechanical condition, if your vehicle is in poor condition, putting this chip in will not make it a fire breathing monster your neighbors little kids will be afraid of...  more likely it will run even worse.
