I installed my Apten cold-air kit last week at the same time I put on my Steeda Cat-Back.
I picked up 10hp SAE corrected on the dynojet dyno from the cold-air and then another 10hp after installing the Steeda. I don't have a tune or a pulley yet. I think the cat-back would have seen a bigger difference on a pullied car.
I am very happy with this setup. The car sounds great and has a better throttle response. The 20hp extra are a nice too
My air/fuel was off the charts (below 10) by 4K RPM so I am in serious need of a tune! Pulley and tune at the same time. For now I'm enjoying my 392hp!
