Tuning the C8
It is my understanding that the C8 cannot be tuned because the ECU is encrypted and locked. Witch I understand GM/Chevrolet wants you to buy the Z06/ZR1 if you want more power and performance.
This is not fair, I would like to tune my C8 and Run it with E85. Also maybe modifying the engine for more Power
Does anyone have any input on tuning the ECU?

No matter how much power a vehicle has, there are still people who want more. I don't get it. Why not buy the car that has the power you want instead of modding the lesser model you shouldn't had bought? I have a GS. If I want more power, I'll buy a Z06. If I want even more, I'll get a ZR1. You can't have too much power while driving to the grocery store.

How about, I don't want an extra 100 lbs of SC BS on the nose of the car? How about I like NA? How about I like high revving NA engines so I am going to build a de-stroker for the GS? What am I supposed to do, buy a 911 GT3 to get that because it fits into your worldview? Just sayin'. Some people just like to tinker to make it their own..... That said, I am falling back into your idea because I have too many projects already.....

There may be simple solutions to obtain additional horsepower for the C8 instead of a tune. Technology is really pushing these new cars to the limit to where you really don't have to do that much to go faster. 2.9 0 to 60 mph is crazy fast for a 495 hp car. And due to this claimed hp the car has to flatten out somewhere. On this particular car, I would just do safe bolt ons and let it be. Just my .02.

PS: That extra weight on the C8 'Z06" will be on the back!
But I agree rather have a high revving NA engine!

Tuning and a cam will be the easy place to get improvements. The intake and exhaust are going to be darn ideal already.
Would be cool if GM offered some sort of key to allow you to tune, and at the same time acknowledging that you have lost your drivetrain warranty. But I wouldn't count on it.
I enjoy a tuned car, they just feel more alive. Often more eager feeling than the stock higher power version. As such I've tuned every personal vehicle I've ever owned including the 3 I own now.

I get that. Putting in aftermarket floormats may still be legal.
