I'm having the same issue. cant figure it out either. Bump for some help!
Interesting problem. I noticed today that my A/F ratios were all over the place on deceleration when in gear. Injectors should be off. I believe TPS was at 0. When I noticed I decided to monitor A/F in open loop and saw it was normal then it would go rich then normal.
Oh, and I have a high idle ~1200rpm.
Possibly O2 sensor or TPS?

I had a similar problem, ended up being my air/fuel sensor
Slip.. Running your KAL right now as a base tune and am not having any of the AF / TPS / Idle issues you're reporting.
So far the only changes I've mad are ticking up the Idle vavle duty cycle two notches, and changing the rev limit.
I think your issue sounds like your TPS, since on decel in gear im showing a stead 32.x AF on your tune.
send me your datalog? mugenep3@gmail.com - vac should be lower than -22 to -24, duty cycle will go to 0 and a/f will shoot to 32 until your vac/tps/idle is normal speed and your a/f will go back to 14.7
I changed my TPS with a K-Tuned TPS and I still see the dropouts, however there are much fewer...
Good stuff. Does the tune work ok? IE: Decent power? Send me a 2nd gear 2000-8000 rpm datalog and I'll graph it for power. Make sure there is little wind and a flat, smooth road.
