Not really sure why you're getting big problems, but the DSMLinkv2 user guide says that dead time for a set of denso 720s should be close to 450.

Of course if your long term fuel trims are looking good then you might be fine on that note.

just input the proper injector size instead of trying to compensate

we made it to compensate and it still took a crap on me
i put the 550 injectors in andeverything ran good except my injector duty 107% but anyway what do you think?? injectors are bad?
