Completely happy with the LET pulley, LET tune, and K&Ns for now.
I want a CAI but I also want to keep the factory look and IMO $450 for a powder coated tube is a bit much. Nothing personal against NW I know these are low volume and hand made. Track times are great and all but on the street is what I care about and the pully/tune make a big difference and add more enjoyment to driving.

(also my tune was the same price as your list - so price is not a factor on the tune)
