Rhino had to work on some other stuff Friday/Saturday, so just getting back to it. So far just tweaking the AFR and timing he's up to 262 RWHP. They are working on an issue with the throttle position below 4K RPM. It appears to be limited to 60% which is limiting the commanded torque. That may be because of the intake design, in which case they won't gain much, but if not they may be able to add some low-end power. After that they will do the VVT timing and we'll have a nice 87-octane tune. We'll then do a 93-octane tune once we put in the new in-tank pump (gotta drain the tank anyway).
