Maybe the 1M doesn't have this protection in ECU, because it is an M. But if you say that it bogged... Maybe you can try to fast shift 3-4 at 6500 - 6700 rpm. I am sure that it will bog again. 
Let's see what others 1M owners have to say about this. |
I have shifted a few times from 3 to 4 and over 6500 rpm, never noticed anything unusual...yet.
By the way, to Mr. Roboto, if I remember correctly a stock 1M in 3rd can only reach to 181 km/h at 7000 rpm not at 6300, so either your car is with a strong tune or the speedo is showing way much more than real because my experience is also in paralel with stock numbers, I shifted many times around an indicated 180 (which means the car was doing in reality around 170 -175) and it was 6700-6800 rpm.
