P0300 supercharged 6.4l

[Stangguy]

Having a weird issue i can't trace down. Want to see if someone else has had this issue. 14 jeep 6.4l with a procharger on 8psi. Newly built motor. At high RPM triggering a p0300. Logged cylinders 7 and 8 showing misfires even though doesn't feel like it is. Put couple set of plugs 6510s gapped down to .028, tried coils, moved injectors and still can't get it to not throw a light. I even raised the monitor to over 7000 rpm and disabled the p0300 code and it still flashes. Compression and leak down on motor are good. Any ideas?2014 Jeep Cherokee - Ramon - test2.hpt
