Over the weekend i dragged with friends SL55 AMG and on multiple attempts with / without launch control the Z4 with ESS tune smoked the AMG. I feel the 0-62 time is around 4 seconds.
The stock AMG is around 4.5-4.7 seconds so my ESS Z4 should have been around 4 something to take a lead.
Also huge improvement to the 100-200 kmph timing
