Rich at low load little trhottle

[Tsuchinoko]

Hello,

I have a issue i'm passing thru, i have my map tuned, the car is running very very good BUT sometimes at a very little throttle the afr reads very rich.
The first column is tuned for about ~13,8 - 14,2 and it reads ~11,8 - 12,4 sometimes richer that this, sending the traditional sound by the exaust pop pop pop.

I think is something about with the TPS, by the moment my readings are:

Fully closed: -1,33%
Fully open: 100,22%

I have the overrun fuel cut at: 0,5%
And the delay at: 300ms

The map table is stock.

I don't know if the injectors are not stopping suplying fuel or something like that...

This issue started after i upgrade to the beta version 1.4.7 but i already made a test with the 1.4.4.1 version and the issue still and then i returned to the 1.4.7 beta version.

Somebody have a clue what is going on?
