Z800 flat spot

[webbo]

Hey guys, i have a 2015 Z800. It has developed a flat spot when accelerating, bought a new aftermarket exhaust (screaming demon) hoping that would help but still the same. I was thinking about a chip but don't want to keep throwing cash at it if it doesn't fix it. Any idea's

I wouldn't know a Z800 if it ran over my foot, but if a stock bike with EFI develops a flat spot then you need somebody with the appropriate scan tool and knowledge to diagnose the fault.
