So based off of the leaks and all of that good stuff we've been watching, apparently there are 3 modes.
Mode 1 - 757hp
Mode 2 - 815hp
Mode 3 - 1023hp
Now I'm finding that last one hard to believe but apparently if you run 100+ octane and get the pcm demon crate bundle to run it, you can achieve 1023hp. We'll find out with the official word soon enough though, if that's the case, these slicks they have on there still won't be enough
