    Install the Hitachi high flow fuel injectors that came with the VF kit and see if that fixes the problem.

    It comes with the Supercharger kit so why not try it? Good luck.

    Usually when your shop does the install, they have to do a couple of pulls and record the data and send it to VF for Fine Tuning. I would assume that any tuning issues would have showed up then. Was this done or did they just do the hardware installation, download the standard VF tune and give you the car? I'd hope that your shop is ten steps ahead of most people here giving you suggestions, but it never hurts to ask questions. I'm in a Gen 1 and have absolutely no issues; even passed NJ inspection. Good Luck in getting it sorted out.

    Yes they did a pre and post install Dyno runs. On the Dyno hard runs are fine. I just have car at Audi now getting new plugs and coils. Hopefully this will solve all misfires. I spoke with Nik at VF and he says this year car doesn’t need the Hitachi high flow injectors. He wanted me to run some logs for certain things to test ignition, injectors, etc. But before I take it to California I thought I’d just change the plugs and coils.
