I just got some dyno pulls done yesterday and the graph looks like something is wrong. Compared to other dyno sheets online my power seems to drop off sooner than everyone else.

Car is a e82 dct with fbo and running stg 2+ 91oct

Yeah totally normal. You will see your boost drops fast in the top end of the rev range. This is typical for a stock n55 turbo.

I have to double check my logs but I believe the correct gear to be in is 5th. Either way log looks clean especially for 91 and seems like your car is running good. Just remember to shift around 5500 to5800 ishto get the fastest time in a race.

That puts my mind at ease since the dyno operator was saying it doesn’t look right.

These were 4th gear pulls as I wasn’t too sure what it needed to be.

I really didn’t expect to make almost 350 on the 91 map. Guess upgraded inlet and outlet makes a difference on stock turbo.
