EVO9 88580714 goes lean after gear change

Long story short, EVO 9, stock injectors, only few mods. On 88580714 tephra V7.
Do a pull in 3rd gear, if you put in 4th gear and gently push on the throttle, the car goes lean for one second and "jerks".
Sceenshot of the log attached.
As you can see IPW looks fine, so I really don't understand this lean condition.
If you go half throttle or WOT after the gearchange everything is fine, no jerking.
Ideas?

I have tried a stock rom, 88840017 (it's an EDM car), with the same tune of the V7.
The problem on 88840017 does not occur.
Anyone on an EDM converted to 88580714 have the same problem?
