    Peak power on the 575M is at 7250 rpm, to it make sense it would drop off above that, even at redline of 7500 rpm. Going a bit higher keeps the average up after a shift, but too much higher you found out what happens.

    That makes sense. The butt-dyno can really feel the power falling off the closer to 8k it gets in higher gears.

    Viper was 9.37, so it still has quite a bit of time to make up and ideally I'd prefer the 575 to beat the Viper. Currently looking into 550 exhaust manifolds as they should be a direct bolt on. But require some modification for o2 sensor placement.

    Dropped the 575M off for service ... insert 40 year old virgin quote here.

    The following day:

    Corner balanced, suspension tolerances adjusted and aligned.

    This is after losing 150 lbs and half tank of fuel. . . porky. Ferrari claims 50/50 weight distribution. lol

    Ti exhaust is looking beautiful although unseen.

    After the corner balance and suspension adjustments IT IS SO MUCH BETTER. Its neutral in the corners with much more turn-in grip. Comfortable ride characteristics. But my girlfriend is still reminding me that her car is louder & faster

    I forgot to mention. There was a strong fuel smell after filling the tank and taking a hard corner. . . so Mr. Steve Maxwell (Ferrari genius) popped off the rear trunk panel to see fuel remains from the fuel pump assemblies, but ran a smoke test to ensure that was the issue (and so he wouldn't have to deal with me, lol). Per usual, he was correct.

    For the past few months I've been living without the carpet cover in the trunk (because it needed to come out for the pumps) and now I'm dealing with the carpet cover which .... takes up space and has zero soul. I am debating on reaching out to a local carbon guy to make a carbon version of the factory yellow/orange panel under the carpet that covers the tank. If anyone is interested, let me know as I'm sure he will likely do a single run. To be clear, I don't think this will offer any noticeable weight loss ... and its in the trunk, so its not seen often. But will fill my unreasonable wants.

    I suggest going to smaller, lighter front wheels and tires with help with acceleration, especially at high speed.
    it won’t help handling but engineering is all about compromise

    Yeah, that would definitely help the straight line. I debated on throwing the stock wheels back on the front to see if it was quicker (heavier but the tires are skinnier, 255 vs. 305, and have less rolling resistance). But I'm about an all around car, so compromising straight line speed for handling and braking.
