I’m at a loss here because the car drives fine at all other speeds. Strong acceraltion up till that zone, then strong again after 200 km/hr. The Audi tech says he’s reluctant to start throwing parts at it like new wiring to the ECU or a new ECU... my quarter mile times have only improved from 11.7 sec to 11.4 as my best. This supercharger kit was supposed to get me to 11.0 sec and it feels like it will if I can resolve this issue. Any suggestions?
