    The profec is good for at least 2 to 2.5 bar if my memory serves me right. Thats 30 to 35 psi odd PSI

    All that and you still have a JWT tune ECU? Is it a proper tune where they put you on a dyno or one of the "drop-in" chips? Cause you should really get a proper tune otherwise.

    Ah fair enough. Winter is the best time for a tune though isn't it? As in summer, air expands so you'll just be running richer if anything.

    But those are heavy mods you've got there. Be interesting to see what it runs on a dyno. Have you tried to start her up since the rebuild you've obviously been working on? Sounded nice? Be interesting to hear a B&B system. Are they the Labree that split all the way down or the "half-split" type?

    In the product feature list it says "controls boost up to 43.5 psi"

    2 bar, 29psi

    Heard rumours that it doesn't hold over 20psi with much stability though.

    With the amount of money you've spent on your car why would you go with such an old controller?

    Sell it and get a Blitz ID-III.

    :zlove:

    Winter in Canada (some places) = freezing your coolant and split your block and radiator. I expect that's why it's in storage ;)
