hmm, i'm not about to throw a cheap ebay CAI into my car. I hear the aluminum piping just turns it into a "hot air intake" and i think that would be more of a compromise to my engine than running a tune. also referencing the warranty statement, i have a manual and i heard running a tune doesn't void your warranty? also the tuner has an option to set back to stock, so then how would the dealer presume it's been altered in any way?
How does the tuner increase MPG if it also increases performance? wouldn't MORE performance mean a decline in mpg?
i'm addressing multiple replies in one reply, since it saves me time
