I had the same intake with the X14iED's. It still ran a bit too lean, as I had a lot of decel popping. I'd still consider trying them, but you will more than likely have to add an additional tuner if you have an aftermarket exhaust too. I ended up taking my intake and FuelPak off because I didn't feel like screwing around with the tuning anymore. I lost a little power and it doesn't look as nice, but it runs like a champ now.
