Well of course it is only just an intake tube, and does nothing for the MAF tube. Therefore no size increase or decrease with MAF tube=no tune required. I foresee maybe 3-5 hp at most, none of which you will feel at all.
true but with my mike rousch tune i can get a revision for the intake tube and perhaps pick up a few more. 150 for 5-8HP? thats not bad at al considering alot of mods in that price range produce the same result.
