I have a 320i and it’s my first car ever and I decided just to do some pulls with it but I noticed when I’m pulling on the highway and I go into 6th gear the car likes to not give me much power almost like it looses boost or something like that. I do feel like I have boost when I’m driving normally in 6th gear but only when doing pulls does it have that problem. 1st 2nd 3rd 4th 5th 7th and 8th gears all feel fine. I wasn’t sure if it was my tunes or not. I have a stage 2 93 BM3 tune with a high flow downpipe and a intake. I have a inter cooler,charge pipe and boost pipe on the way right now but I would like to have an idea on what it could be
