His would be a good engine to put on the dyno as it has Stage III Prechambers and the cam, (valve train), is advanced a touch more than new spec.
It has "unmolested" injectors at the 135 bar pop pressure and I would prefer to run honed injectors at 150+ bar. It did run very strong, revving very quickly, and the boost came up quickly as well.
The car owner works at a pump shop, and we were told as long as we were not charging for the work we were doing, that we could use a back up machine in the back to play with. I put my digital interface setup on the machine so I could get a baseline fueling curve, as I wanted to see the difference in performance with the same fueling curve, but larger elements.
I did put a stronger spring in the Torque Control Capsule to help match the fuel curve, but other than that, the settings are very mild and I was able to match the base line fueling curve +-.
We may pull the pump and tear it down for an inspection and then I would want to grind the cam.
