It's all in the tune. Having the car properly tuned on a dyno (by a good tuner) can make or break your engine. I've been running an 8lb set-up making 400rwhp/386rwtq with a very conservative 11:1 air fuel ratio. That was with a wimpy BD-11A Powerdyne though. With the NOVI 2000, I would recommend an upgrade to 42# injectors to support the hp levels that blower and your car is capable of. I just went with 36# injectors with my new head unit and I don't think they will be enough without the fmu. Once the blower is on, I would recommend not getting on it until the car is on the dyno to find where you air-fuel is at. That way if the tune is off, you can avoid things like a blown head gasket or even worse. Good luck.
