    Three things : 1the throttle is not sensitive during the cold start , rpm won't go right up when full throttle.
    2: The scud is lack of power soo much , first gear full throttle, the rev goes up soo slowly, by the time to change second gear , FT86 by my side has pulled full car length ahead of scud
    3: the car has its full power when the water temp reaches 80+

    Is my scud normal? It can't be this powerless during the cold start right?

    I don't believe this is normal.

    You may want to bring to a dealer or independent with a SD3 to reset the ecu parameters. If the ECU does not know the correct parameters (ie for a given ambient temperature, the timing, airflow, fuel etc should be a desired value) you will notice severe performance problems.

    I doubt the fuel system is your issue since you have full power at a given temperature.

    No power during the cold start procedure is normal, therefore my recommendation: Don't drive the Scud while the engine is in its cold start program!

    We talk about a highly developed and demanding sports engine. Always wait until the engine reach a round and stable idle! If you do it anyway it may be that the engine does not come out of this program for a longer time and the car drives like with a broken engine (no power, not a normal throttle response etc.). Then the only reasonable solution is: stop the car, turn off the engine, wait a few seconds, start the engine from new and wait for at least 30/45 seconds until the car falls into a round and stable idle.

    The ECU is likely protecting the car from your abuse. Do not drive the car hard until the oil is up to temp.

    Why would you want to rev or command full throttle with a cold engine? Don’t do that...

    Make sure the battery is fully charged when you start the car. I had my scud in for annual service at the dealer and forgot to tell them that I'm using a lightweight battery that should be on a trickle charger. When I started the car when I picked it up, there was very little throttle response. Once I drove the car around the block and got some charge in the battery, it worked fine. Could just be a coincidence, but I suspect it was a matter of misfiring because of little or no spark in some of the cylinders.

    Based on your lack of knowledge of the Scud, please sell it and get yourself a Nissan GTR. You'll be MUCH happier and Ferrari will thank you for it.

    Keep doing this and your engine will die a painful and very expensive death....
    It could be normal (as Mark says to prevent abuse) but I’m not sure many will have tested it!

    Revs below 3-4K until the oil temp is on the gauge.
