hi guys i need some advice from cars expert or mechanics.. i want to add an intake air system for my gs300..but doesn't know what is good..I look at the srt with some air/flow ecu chip. do i really need the chip...the entire system costs like $500..that is too much..do u know any alternatives? also I've read one of the forum..some one said they reset there ecu by pulling the fuse and battery cable out..why? i don't understand why you would have to do it..
