Until I see some dyno numbers, I refuse to believe that a K&N/ABT/RamAir filter will give an additional 7-8 hp with a chip and 10-12 with chip & exhaust. Frank Wetteraeur himself feels that a cat-back exhaust is only worth 4-5 hp with a chip, how on earth could a filter give 10-12 more? By the way,I've got a 1.0 bar Wett chip with an ABT filter.
