I just dyno'd my AFE stage 2.

I put the intake in and drove around with it for a couple of days, then stuck it on the dyno. Made 365/366rwhp. I swapped in the stock intake tube and the stock 2011 air filter (basically brand new) without the carbon filter, and made 360rwhp. So, 5-6rwhp difference.

Not a huge gain, but it's there and it's a touch more than the dropins make. I'll leave it up to you to decide if it's worth the money... I'm gonna put mine up for sale.

Here is the dyno chart showing the difference. Run003 was with the AFE and Run004 was with the stock filter and intake tube.
