I currently have a K&N drop-in with the bottom of the stock boxed opened up. Wiith my currents mods of TB, SMIC and Unichip will I see any gains by upgrading the intake to a CAI or SRI? I could not find any dyno results of intakes. Would it be even worth upgrading it after other mods like the 626 IM or hardpipes? Not concerned about looks or sound
