Good move the APR R1 is supposed to be a really good valve
Thats probably best untill you fit it. Splitr has bad piston design causing it to leak, but you already know that im guessing.
I would have kept it anyway if it weren't for the tinkering bug Did you remap it with the splitr mounted?
I got one last week used it for first time yesterday, brilliant results.I desperately Need a machine polisher!
