Fuel lube? Since it's a two-stroke, you gotta mix oil with the gas. 
How about "fuel lobe"?
It's the lobe on the camshaft which actuates the fuel pump.

The lt1 and lt4 engines have an extra lobe on the cam that drives a high pressure fuel pump.
The upward and downward difference on the fuel lobe (11+ and 32+), are for a stock/aftermarket setup on the HP fuel pump, which includes a lash-cap.
How much power do you plan to make with this car down the road? Then myself and other's can give you advice... but yes, you will need a fuel lobe on your cam to run the factory high side fuel pump
You probably don't need the bigger lobe however, unless you want to make more power later.

Are you sure its not "fuel lobe"?

the 11 and 32 are indicating extra difference in travel. It makes the stock pump work harder to pump more fuel.
However, a lash cap is needed. I don't run bigger fuel lobes personally, I personally achieve more fuel flow doing other mods to the car such as port injection.
But, if you are already replacing the cam.... it might not be a bad option to explore.
who is building your car? What other mods are you going to make to it?

i would highly recommend keeping the cats in your x-pipe, or else the car is going to be very loud.
Have you heard one yet without any cats on the headers and none also on the x pipe?
Who is doing the engine tuning? Do you have an auto or a manual?

before I bought a single part for you car, i would find out who your tuner is. Automatic transmission cars are a nightmare to tune. There are only 3 people in the USA who I would trust to do it.
The transmission needs more tuning than the engine, the TCU is the brain to the car, it overrides the engine tune and limits the car's power, and most people have no idea how to tune the trans.
Figure out where and how you are tuning this car, otherwise, do not install anything more than an aftermarket intake on the car... and definitely not a cam, unless you are only after the sound, and not power. But it still needs a good tuner or else you will blow up your engine.

If your goal is to make more power, or go to the drag strip and get a fast time, then ask him who in the USA has taught him how to tune the automatic transmission on the c7... because its new info most people do not understand.
Many of the tuners here in the USA, at decent sized shops, are still learning how to tune the auto trans correctly. It is not easy.
I would make sure he has one of the good tuners here in the usa double-check his tune before he gives you back your car.

Who are the three tuners that you would trust??

Since I am a vendor, you are causing me to play favorites and put others down in the process on the open forum if I answer that question. I can't do that.
My point was simply, I doubt there is a person in the middle east that knows how to tune the trans well on an a8 z06...
would you agree?
Also, if you have any recommendations, I am always willing to expand my horizons and add a 4th or 5th to the list.
It would also help the OP and his tuner perhaps if you have someone to recommend.
If the OP reaches out to me for more info in PM, I will provide him my opinions.

That's an odd cam for a supercharged engine. You should do some research. That looks more like an NA cam. Also, if your car is an A8, pay close attention to the cam you select. Bigger is not better.
You'll want the 32% lobe for more stroke on the high pressure fuel pump.
Sounds like you need to call a pro and get a recommendation for your combo/plans.

Make sure he understands that the airflow model needs to be perfect, don’t cheat anything on an a8 car when it comes to the tune. Yes, the trans needs tuning but VE and VTT need to be close. There is a video out right now of a 2650 Maggie car who’s trans “ate itself” on a 9.20 pass. You got that? Ate itself... it’s obvious that it’s a tune issue when you see the vid.

Making friends with the top tuner in the middle east might be a lucrative friendship Mr. Hebert. You would be surprised how often they pay a plane ticket to get a person flown over who knows what they are doing. Back in the day, they used to hire planes to come to the USA and pick up their cars before they had a strong dealer network.
The people over there have money.
