I run this motor.
Haven't really done anything to it yet, as my kit is relatively new.
Do you remember the stock settings for the high and low end needle?
My friend helped me tune the engine after break-in and we forgot the settings.
Currently having a bit of problems after putting my car away for 10 days (yes, afterrun was added)
Engine is NOT revving most of the time.
Just get a deep exhaust note, and the car runs at a super slow "break-in" speed
