Lean AFR Problem

[nm2769]

Ok guys I need a little help. I missing something here that is causing the AFR to go lean @ 4000rpm with 30% throttle. My log shows that commanded is 13.84 and the WB02 is reading 15.15(frame 186). I made several logs to verify the lean condition and they all showed the same results. Lean @ 30 ~ 40% throttle. So I adjusted the TPS VE table to correct the lean condition and it made no difference. Still lean. Attached is the original tune and log. Thanks in advance for you input.

Thanks
Nick
