Dsm 16g blew hole in intake coupler - YouTube

Second gears going out so i do a slow acceleration, shift into second and floor it around 40 miles an hour. Slow shift into third also and blow a hole in a coupler after noticing in third I was loosing boost and you can actually hear it blow it around 80 miles an hour.

The question I have about it is with the AFRs. Im sure yall noticed at the higher rpm range in second gear it drops to 10.1 afrs. In third gear its pretty much at 11-11.5 afrs and dipping into the 10s here and there which I need to tune out. Is that normal though and is there nothing I can really do about rich and or lean afrs in lower gears because were always tuning for third gear pulls?

In other words as long as I can get afrs around 11 at WOT in third gear is it normal for them to be different in different gears?
