i think a few people off here have had them and theyve worked, not major gains but they do help the responce problems...
the resistor type 'chips' that are for sale on ebay are the shat things that are just a resistior that plugs into your airflow meter plug... these just increase the amount of fuel going into your engine by making the ecu think its cold, and more air is entering than it is...... load of shat really.. they sell for about £3.99 lol
wait for some one who has had one to see what there responce is... then decide... £24 aint bad i dont think......
