300hp injectors...not +300 hp

 

also, try a differrent boost elbow, and maybe a boost fooler. they allow your turbo to provide more boost and spool up faster

 

I tossed the ring, and put on the buff air filter(cut the airbox down to cradle the filter with the end at the cold air fenderwell scoop.) The turbo is now quite evident spooling up or down, and is definitely the sound I was looking for. Not too intrusive, but audible at speed as well as under acceleration.

 

I def agree with the above^^, removed my silencer ring, put on an AFE torque tube and an amsoil BHAF with a pre filter. Sounds like a 747 when shes spooling up, love that turbo whistle!
