It's the new chain included in the kit from EVO Industries. EVO has the information on the gearing posted on their site, I haven't tried it yet so I don't know where I'm at RPM wise. I know that I'll lose the 6th gear light as I did with the EVO 30 tooth I just took out. I didn't lose cruise with the 30 tooth so I don't know if I will or not with the 49 tooth. If I do I will get it back with a TTS when I convert the SERT to TTS. I'll post an update once I run it.
