where is the wideband o2 sensor located? Do you have a cat and an airpump?

 

more then like one of your pri inj is cloged or u might need to upgrade to 550 or get a AFC

 

wideband is about 28 inches behind turbo and no cat or ap
sojin i had new in box injectors in primaries and still same problem but the new ones were 780 cc and still not enough fuel and ecm is programmed to run stock primaries so it should have been rich with 780s
