Because on both of your dyno stats, the blue line (which has the K&N) has the higher number of air fuel ratio.

now you got me thinking if their wide band lambda sensor is just fux0red?!? see.. both brad's and my A/F is exactly the same (blue:blue, red:red)... maybe just a calibration issue?

for the Air/Fuel ratio,
the closer the Line is to 10, the Richer the system is.
those Spikes in HP, correspond to a spike in a Lean A/F curve.., maybe that was a detonation fluke.. because your other runs seem to be quite smooth.

more air = leaner... this is the case with my run.. injen lets more air in than k&n
brads is the opposite... he got less air in, and it looked to run richer...

Has anyone tried the procedure in the service manual to "re-learn" the air fuel mixture. I've done the procedure but can't spend money on a dyno until after my new 5AT gets installed (started whining and shifting a little out of sync).

I used the $7 FRAM to prove a very simple point. You don't always get what you pay for spending money on "performance" filters!

theory:
our stock fuel/air mapping is already lean(-er) than normal.
hypothesis:
due to the induction of a higher free flowing intake system, there is more cooler / denser air getting into the engine. thus creating an even leaner fuel curve. engine senses this, and retards ignition to prevent knocking.
data:
skidazzles zero gain w/ injen intake after running 300+ miles on it. other private dynos that have displayed little gains.
conclusion:
our hypothsis can not be proved just yet, with my ECU being dissected and changed, the research/results might yeild more conclusive answers at a later point ~2weeks after the car is dyno tuned and ignition/A-F changed from stock
any thoughts?

Still, this does support the dyno sheets since the FRAM got the A/F ratio closer to 12.5 as compared to the K&N.
