Well, I had the Trick Flow street series intake making 473rwhp at 7psi. I changed to the TFS R series and i can tell you is a 20hp to 25hp difference, the car revs faster. I think you will benefit if you change to it. The only bad thing is that when i got mine last month the Black finish upper and the Silver upper were on back order until late March, so i ended up with the Non-Powercoated one, and i am happy with it.
