I have a 2011 Apex 128 with 1100 miles on it. I have an Ulmers airbox mod and PCV with Ulmers map. On a long WOT run, my rpms are between 10,400-10,500. Is this about right given the amount of miles I have?

Thats right where my mine ran at that mileage. Now at over 3k miles it runs about 100rpm higher. 10,500-10,600.

Wow , just how many miles does it take to loosen theses motors up , and what peak rpm should they top out at before horsepower starts to drop off
I think mine was around 2000 miles it stopped changing. It runs around 10800 rpms on long runs
