Hi!
I bought my first BMW and it's 2015 F30 328i 245hp.
Seller said me the car is after chiptuning and I tested it today on dyno and my BMW have 289,5hp.
But my 0-100km/h is 6.4s and with 100 gasoline my best is 6.1s..
I saw many videos and posts and it's look like my car supposed to have 5.5 cause 6.1 is serial right?
People in dyno says me the car works great but why 0-100 is so low when I have 289hp?

A dyno test has nothing to do with the factory specs - 289hp on the Dyno means about 10 - 15% less on the axle - that would be 245HP
The stock specs for a F30 328i are 245HP 5.9S 0-100km/h

Looks like you have a stock spec 328i.

Here is my chart


So even torque isnt really 440 on road?
What should I do?
Make chiptuning in another place?

DYNO log looks fine
Do you launch? What tires are used?
Good tires can promote 0.8-0.5 seconds.
Also means bad tires will be 0.8-0.5 seconds slower

I have Michelin Primacy 3 and now I see these tires have a poor reputation.
Also they 3 years old..
I will buy Michelin Crossclimate cause I I want to have all season tires.

Last one interesting fact is today I get XHP Stage 3 and now I have 5.7s!
Also fun of riding is so much better.
