No fuel at decel

No fuel at decel
Hi guys, another weird one for you.
Right now, Fuel Cut is turned off.
I let ve analyze loose on my tune and it is adding crazy amouts of fuel on low kpa's (decel)
With the numbers below, my afr is reading about 17 AFR at 1.5k rpm on decel.
Why is this happening?
I'm pretty sure I don't have an exhaust leak.
Thank you and kind regards,

Hi guys,
After months, I finally found the solution to my problem.
Because I have an 1990 1.6 engine, it was running batch/semi sequential injection by default.
Wiring up fully sequential injection (have an MS3) instantly allowed me to idle at 14 afr without surging.
Problem at decel is also resolved.
Once you go bigger injectors (i have 560cc), sequential is a must it seems.
Kind regards,
