Larger gains with the intake, but a little more power with exhaust. I agree, they do need tuned as well -- 11:1 at WOT is pretty rich...
Great job, Thanks for sharing this with us.
One last thing. Go Rockies!!

The 11:1 ratio is probably a little lower in reality. Instead of removing an O2 sensor and using a wide band sensor to get a true reading we used a sniffer attached to the dyno so we would not get a check engine light on the truck. The dyno operater felt the actual reading should be near the 10's.
