I have already ordered two of this turbonator for my E55 and i want to know is this useful or not since I'm using ITG racing air filter, iridium spark plugs and 100 or 101octan fuel maybe this will give me more air to burn this type of fuel ?
I have one more question:
Is it better to remove catalyst for more power?
This is the site of turbonator:
