I'm sorry guy, but I just can't imagine the carbon fiber airbox giving you another 15-20 hp, the stock version might be a little restrictive but it's not that bad. I smell BS. Maybe you can post a dyno after your full tune.

This is going on a stock crossfire right, and not the srt6? I think with just the SL55 y pipe on the srt you can pick up 15 hp for only a $45 part.
