Recently installed HR CAI and S2 Header.
Did all of my part throttle tuning with no issues.
Then started fine tuning WOT.
There is really only one area I am having trouble with and I think it is an issue with the AF corrected or my AEM wideband.
At the 5:30 mark I do 2 pulls. Right between 4500 and 5000 I can "feel" power loss, because at 5000 when vtec activiates I "feel" a big power jump.
My AF corrected reads a steady 12.4 but my AEM UEGO dips to 11.5 in the same rpm range.
My opinion is that it is the AF corrected is wrong at that point. However at 0% throttle the AEM is all over the place.
The AEM was on my sti for about 15k miles. At idle it typically reads 15.0 when in my sti. Now it is reading closer to 15.3 on my si.
My calibration and datalog are attached.
Thanks for the help.

Re: NEED HELP! Bad O2 sensor?
Both your AEM and stock O2 sensor are bad. Pretty obvious...
