So,
I have a annoying problem with my N54.
Everytime I accelerate with WOT from lower RPM's (everything under 3000RPM) it feels like the handbrake is pulled and then released about a second after I push the pedal to the floor. In the Moment that second of hesitation ends, when the car starts accelerating as it should, I can feel a short shrug.
Another thing I recognized is, that the car keeps accelerating for a second, even if i lift the foot quick of the gas.
Feels like something's not acting fast enough.
Since I'm knew to the N54 I did some datalogging and looking forward for you to help me.
I really want a pro tune, but I need to be sure the car is allright before :confused:
Some Facts that might be interesting:
135i '08, new Turbos, new plugs, inlet valves cleaned, 4 injectors and HPFP replaced some time ago by BMW, cleaned and switched the vanos solenoids today (no major difference).
I'm running the Wagner FMIC, catless DP's, Performance Exhaust and Map is COBB Stage2+ v402 on 102Octane (I live in Germany).
Sorry, If my english is partly hard to understand. I hope you get the plot.
