stretch when I said the ecu would need to be tuned differently I was saying you shouldn't just plug in a piggyback with a basemap. The stock ecu compensates for a cai with no problem but if you are leaning out the mixtures with an ecu tune you need to consider the cai is present. Considering the extremely large number of ms3 owners that have a ms intake I would assume that most companies will make a map available for it. I happen to think cpe makes great products and would not have a problem buying from them, in fact I think their intake looks nicer than the ms intake and in all likelyhood could produce better gains, but it doesn't come with a waranty and could void the waranty on my car. So instead of getting a cpe that I would have to remove every time I went to the dealer I will go with the ms. I just don't understand why you are bashing mazdaspeed especially when you don't have a clue what you are talking about. You seem to base your opinions off of same statement cobb or cpe made, which doesn't make you an expert on intake design. An intake is supposed to produce power and lean out the mixture a little. CPE even said their cai leans out the mixture. Why are you trashing are sponsers products when you have no experience with them and are clearly not going to buy from them. That's not cool. If you had some real knowledge and informative data then your comments may be interesting, but everything you say comes out of your ass.
