Has anyone de-tuned a Z06 to the 550 HP range?

Um, I could give you all background on why I'm asking and still 1/2 of your would laugh - so let's get the party started.
1/2 of you - go ahead and laugh - the rest of you - is this easily doable? Like different sized pulleys or something?

Self preservation. I've been tracking my cars for 2 seasons now . - but I've got a stock LT1. Even the stock LT1 is a good bit of power. Really, the vast majority of people on track don't need more than that. And I can just forsee catastrophic power oversteer as being a real thing with 650 HP.
There's got to be a simple detune - like different size pulley or something that takes the LT4 down a bit.

If you leave the Z06 in Dry or Sport 1, it will be really hard to force the car to kill you. You need to use at least Sport 2 if you want to give the car the authority to yaw.
In Dry or Sport 1 you can essentially go 100% throttle at apex and the car will modulate power output to keep the car stable.

why? From what I can tell being a c7z owner These c7z06’s aren’t that fast as delivered from the factory in the first place. They are just plain flat on the big end. No sizzle.

You have to learn throttle control and know what your butt meter is telling you. Yes, PTM can help modulate rear wheel spin to make the most of the available grip coming out of a corner. However, I have only found a few corners where I have been able to go wide open at the apex and not have the back end start to kick out. You can hear PTM modulating the power. The exhaust makes a sound like a diesel engine slowing with a jake brake.

Too easy! Trade in it and get a few dollars back drive home with a GS instead!

Yes, if you respect it. The car will teach you a lot about throttle control but once you learn how to use it and the tires are warm you can absolutely use all 650 HP.

Keep the stock lt1 and add power when you feel you need it. If you feel the need to drive with your foot to the floor buy a Miata. Just remember the gas pedal isn’t an on/off switch. I do some hpde with my z06 and I’m not driving the car remotely close to its limits. It is really nice to have the power to pass when necessary.

About 1-2 percent will wrap their new Z06 around a tree from smashing the gas then losing control and like the new mayhem commercial "JACKPOT" Never throttle up or drive angry! With high power cars!
Silly thread just admitting your driving needs a lot of work!

I think you should stay with unicorns!! If you are afraid of the Z06 you should not drive one. Not trying to be an *** just saying the truth. If you want a detune a Mazda Miata will make a great track car or stay with the stingray.

I would sleeve the intake in some manner. With a 3D printed cone or machined. Like a restrictor plate in nascar. It’s the easiest and easily undone mod I can think of. I wouldn’t go with pulley swaps.

I have been trying to get to wide open but once the back end starts to step out I am not going keep on pushing the throttle down and take a chance on spinning the car there just to find out whether it will or won't. PTM is very good and I use it a lot but it doesn't do exactly as advertised. I noticed in the Jim Mero video of the MRC Upgrade he was using it quite aggressively but I can't remember whether or not if the video showed any looseness in T1.
