Weeeee. Weiboy will do the E90 crowd proud. Can't wait to see what he does with the E90 platform!
Nsquared: perhaps its a vac leak. I'm sure you don't get much power boost in first gear tbh. How is the power in the higher gears? Doesn't the F30 have eco mode? Perhaps you are stuck in that mode? Car is too new to have issues
PS: Happy new year! Wish you all much happiness and success this year!
