Anyone have it?
Good things to say about it?

I know it will be better with a tune, but without one does it work okay?
Gas milage take any hit?

Thanks
Steven

 

Gas mileage doesn't seem to have taken a hit, maybe even slightly better. Don't know about HP, but torque definitely shows up, pulls nicely down low. Waiting on my tuner from Doug to see what else it can do...

 

And no check engine light
- excatly what I wanted to know. Thanks

 

from all the 6ers who have them, there have been no complaintes, and the people who actually dynoed confirmed the claims of AFE
