Im not too familiar with these prodects as I roughly know, once installed, the tend to lean out your a/f mixture so your car runs lighter (feeling more powerful) and saves on petrol but dangerous cos if it's true, I guess you will be revving higher in rpm's but dangerously lean in mixture... :o
Just my two cents worth of opinion...They come cheap too and claim to increase 30% in power, which sometimes I would wonder. Say 30% improvement in hp for a 100hp car would mean just with this gadget, I would have gain 30hp and my horses under the hood is now 130hp.... :blink: ....We sometimes spend thousands in exhaust, air filters, plugs & plug cables and still achive additional horses in the region of 15-25 only and this gives us 30% hp gains...Wonder how they calculate, maybe I'm wrong... ;) .... :rolleyes:
Regards & cheers
