    Making more boost than anticipated

    So for the past month or so I have been installing my ECS Novi 1500 kit on my LS1 C5. Finally finished it up and my tuner has been doing some remote tunes for me until he can get his health back. The last one he sent he said that should work good until he can do a street tune. I scanned it this afternoon and at around 6400 rpm?s I was at about 14.5 boost. From everything I have read, the 3.47 pulley that ships with these kits should be around 8-9ish. I have a stock bottom end so the 14.5 worries me. Here is a list of some of the mods if it helps. Maybe I could post a my tune or log and someone verify that he doesn?t have my engine on the verge of explosion lol?

    BTR 231/244 631/615 cam
    PRC 225cc ascast heads
    660 BTR springs
    1 7/8 Headers
    Alky Meth kit
    ECS Novi 1500 kit
    Circle D 3400 Converter.

    Do you have cats on it? They may be clogged.

    Be sure the fueling is good with that much boost and it is not close to knock.
