Found the issue on cyl 6.  Calibration was off by value of 2 (last digit the first number, had a 6 instead of an 8).  After a couple passes, got the tires hot enough to stick finally in 3rd.  Felt awesome! But looks like a lot of knocking on cly 5 still.  This cyl has always been noisy though.  I've bored scoped it and piston looks same as the rest (no chewing/detonation pits), replaced injector seals, swapped injectors, plugs, coils etc. on it several times.  Only thing I can find is this injector always feels the easiest to remove the injector when i pull it?  Is the head injector hole egged out? But never saw any carbon past the seal when i pull out the injector, so I thought it was still sealing OK?

Regapped 1 step colder plugs to 0.18 (was 0.20). New plug installed in cyl 6. Swapped coil 6 and 4. Ony hwy pull in 3rd to 4th shift after oil was warm, still misfired on cly6. Lots of knocking on cly 5 also. Also found "super knocking" fault on cly 4 after pull? This sounds really bad.
