To be honest Jay, this is the first turbo car I've had and I fitted the DV+ within the first week. I'm still getting used to the different ways and noises this car makes. All I can tell on limited mileage is the CAI adds another suite of noises to the turbo, DV+ and exhaust. But it does put a smile on my face.
I used to love the snorts and bangs my old Escort Cosworth made and every time I add something to this car it brings the same silly grin back.
It's pure fun.
