These "performance chips" are with out one of those cons which rank along with the ppi scandal. It amuses me that folks will believe that after a manufacturer has spent millions on developing an ecu for best performance and ecconmy that someone on ebay can sell a 50p resistor pack for 50.00 as a performance booster because they know something that the car manufacturers dont.
all these things do is fool the ecu into thinking things are colder than reality so it throws more fuel into combustion chamber so it runs richer......Unfortunately most ecu's are smart enough to spot this and compensate elsewhere. Performance is usually the same but with much worse fuel consumption and very rapid engine wear.
