You wont notice any gains, you might get 5 kw if you are really lucky and did a service on the car before it went on the dyno but a good air intake shines on the track. Also the bad bend I am referring to is the 80 degree bend from the TB. Sure thats how it is stock, but that is massively restrictive. Did you modify the airbox at all? Thats where the gains will come from.
