Hi Guys, Just did a Hybrid Turbo upgrade on my F30 320D.. Noticeable difference in power at high RPM's but the car is struggling at low RPM's. The lag is getting to me also noticed the car is significantly heavier on fuel. Have you guys experienced the same when doing this upgrade?
You might wanna start a new thread with a tad more info.
New thread - While a necro is fun, a new one is for you and your problem/s
Hybrid - Who did it and what did they do/upgrade. Was it done on yours or bought secondhand etc etc.
Tune - nothing mentioned, did you get one done after, not at all or it still runs on a previous tune
The lag - more info in the 2 points above needed to get a sense, normally hybrids don't cause too much lag (if any) once you get software done for the hybrid. Logs would be better if you have any (not that I can read it but here are a couple of Einsteins on here that can).
What inlet are you running?

Possible boost leak?
