hfcs
I'd like to start a thread showing mileage of Z's with hfcs and if there have been any problems. I'm looking to get berk's but with the huge gains from the F.I. catback alone (minimal gains with their hfcs) any cels being thrown isn't really worth it in my mind. If anyone's over 5000 miles that'd be beneficial to see how its working out.
