I kno this has been discussed already but i jus wanted to get some more clarification....those chips on ebay that trick ur ecu into believin its suckin in colder air...the ecu compensates by throwin in some more gas...i kno it wont give me 20 hp, but i kno when i reset my ecu a month or so ago, the engine sounded alot better(since the original ecu settings throw in more fuel)...will this chip damage my engine at all....im basically goin for the sound difference but im sure i can get a couple hp
