"Race- Chip" - Performance chips that does not use the O2 sensor.  Fuel is determined by actual air flow measurmets.           Best for all around performance.

"3K5- Chip" - Performance chip with functioning O2 sensor only below 3,500rpm, not above.
                                 Pure performance above 3,500rpm,
                                 Better fuel economy below 3,500rpm than the "Race-Chip".

"Lambda- Chip" - Performance chip with a functioning O2 sensor. Similar to the stock chip but with higher performance mapping for fuel and ignition.
For use on cars that have essentially stock engines with minimal performance modifications if any.
