MY GUESS NOW (blind) is this is BOG only car. not misfiring at all just bogging. (like dragging a huge weight)
is car in USA? if yes harbor-freight has a $20 fuel pressure guage with the suzuki 6mm hose there? that fits all suzuki stock filter banjo fittings. my guess stock filter is gone, and so are the stock banjo's" I cant see your car nor see mods done wrong, or any of that, many parts on this car are super hard to get now...... or very expensive from SUZ
i re-read all your posts.
so the coil wire was hacked. (i see that splice there and is never good to allow that ever)
the injector wires hacked ?
and the ECU replaced right?
back near post 30 ish, you showed fuel pressure ALL WRONG. 18psi is ALL WRONG. as is 20. !!! IF IT IS , ? then this car will bog like HELL.
when did you fix the fuel pressure.?????? I can't find that anywhere. nor how done , exactly....
it takes 2 things to get good pressure, (not counting clogged socks or filters wrong pump or bent pump output side lines and the like.
a good pump that can do 60psi shunt test, (output blocked) at FPR return line, this test in in the suzuki book and on my pump page. Did you do a pump shunt test?
then a working FPR, most this old are dead, and leak. to the return line, so easy to prove. ask./
so if the FPR works you get your 31 to 40 PSI is spec. as sealevel, are you at sealevel
the pressure does not change at wot, like all 16v MPI engines do.
the pressure fuel only change for altitude.
same pressure key on
same pressure, running at any speed.
what is your idle pressure? at idle, and gunned for 1 to 3 seconds WOT.
do you have fuel pressure gauge, does it fit to the filter test port.? as it must,. there is no under hood test point on any 8v. so... deleting the rear one will make diagnoses, impossible.
do not use carb fuel lines or carb clamps only 100PSI rated fuel system parts, are to be uses, EFI rated. or you will get a leak.
here is your system, this is first, as the ECU is wholefully unable to cure bad pressure, nor know its wrong, ever. it must be right.

when you remove the vacuum line from the FPR,does the nipple there leak fuel, is yes the FPR is bad. (they love to fail 3 ways, that, stuck closed or open)
see where the meter sits.
