I read it. Sounds like typical internet
It's not fair to compare the Z to the Jeep GC SRT8 just as it's not fair to compare the Jeep to a GT-R. That being said, there are some Jeeps near 1K hp that are running with some pretty fast GT-Rs.
Also, I'm surprised their 1/4 times in the 2014 aren't any better. I don't think my co-worker had a tune on his (I know he put a Borla exhaust on it), but he ran closer to 12 than 13 the few times he did run it.
