Mods on car: JB4 stage 1 tune, BMS Downpipe... Both these mods were put on last week if that makes a difference. 2011 N55 e92 335i

I was at a red light and wanted to open up the engine once it turned green. I pulled into first and at around 6500 rpm shifted into second. Once in second it felt as if the car was in neutral. Revs would go up but the car was no longer pulling.

I have driven many manual cars (both non-turbo and turbo) and haven't experienced this before. Is this common when shifting quickly and at high rpms?
