I am looking for a PCV tune to run on my RTX, mods are as follow:

Straightline Header
Straightline Can
Stingray airbox mod
Ulmer clutch kit

I run 1000-4000 ft above sea level, aggressive trail riding

nay similar tunes out there? or who is best to call?
 

Awesome thank you! I’ll take a look at it on my laptop tomorrow, I assume you had similar mods?
 
wow, looks like you didn't have many changes above 60% throttle, was this a dyno tune per the name of the file?

It was from Ulmer and I had Excells Air Box mod, Straightline Header and an Excell Pipe. All the mods help the low to mid range more then anything. You can reach out to Ulmer and see if he has another map.
