Here is it again

I have small probleems with JB4. Few times its show me "reduce power".
After few minutes its gone. No fault codes. This problem happen overtime
(engine os cold) when you floor it from higher gear to lower gear and its dangerous. If you're just bypassing another car and then its happen. You cant do anything than braking and retreating to your own lane back because you have no power, but if the another car brakes too, there will be some serious problems.

Its help when you turn of the engine and start it again and you floor it twice and then its work great again.
it seems that every time there is a need for a new adaptation.
I must do it every day.
