I have read that the FMS#19s are rated differently from our OE #19s. They
are probably putting out a bit more fuel per pulsewidth and would explain
the 'incredibly strong' sensation that you're experiencing. They might
also be the reason for your plug conditions. Do you remember what
your plugs showed when you were using the OE injectors?
I would personally pull the plugs now. See and record their condition.
Clean the plugs. Put in the OE injectors for awhile and see if you still
get the same 'incredibly strong sensation'. Then, after about the 250 miles,
pull the plugs and see what their conditions are and compare to what
you had recorded.
I know that, when I was testing the FSM#24s, I too had the incredibly
strong sensation at part throttle but, for my engine setup and operation,
I bogged terribly when I went to a quick WOT ... too much fuel being
dumped in.
Hope this helps.
