ok here it goes
started street tuning d16z6 gt30 turbo 750cc injectors 3 bar map
while i datalog i seem to keep getting a map sensor cel code ever other minute..?? i dont know why just when i datalog..
the other is im only running 9psi at the moment..
my injector duty cycle at 9psi at 5500rpm is like 98% and afr is 11.8
why are the injectors maxing out.. they are good for like 600whp..
i used the same injectors and everything on crome pro and it worked fine.. anyone got any ideas?

did u make sure u adjusted for your injector size, also what fuel pressure are you running? Posting your calibration will help greatly

what fuel pump are you using? what fpr are you using? i would suspect your issue is pressure/flow.

when in boost your fuel pressure should rise higher than 48 psi. at 45 psi static pressure and 15psi boost then the actual pressure should be around 60psi.
Check your fuel system.
