this is what turbo lag is.

ah i have a m340i so forgot about turbo lag.
but you remind me of my Subaru STi. peak torque at 4400rpm, mashing the gas pedal does nothing until it hits 3000, then the car moves, surges at 4000rpm, gone by 5000rpm slows down after that.
if you look at the chart, the subaru sti is turbo lag personified
