who did your tune?

I covered the rear top half of the accoustic foam in aluminum duct tape. to prevent the water issue and also to cut down on noise.

you can really tell the difference when you start the car since the starter is right behind the dash.

unfortunately the decibel app isn't that sensitive. but the foam seems to cut back on a lot of the noise produced by the air turbulence going into the intake.

on the soot smell i can't seem to get mine to produce any smell even when i turn off recirculate and crank up the heat. Im guessing a lot of gunk burned off trough use !
