Data log with weird RPM oscillation

Hey guys,

Did some data logging after a weird oscillation started to appear on my Cobb E30 OTS map. Take a look and let me know what you guys think might be causing it. I have DP's, IC, and exhaust on a e35 mix.

two different logs in case they caught something different but they both look similar to me.

Definitely the clutch getting overpowered... It's a good problem to have

BTW, we carry SPEC clutches and flywheels and will match ANY competitors pricing.

Awesome! I will keep you guys in mind in the coming weeks as SPEC is the brand that I'm going with.
