Running lean but shouldn't

[CSEclipse]

well i installed my afc-2 and i have 660 and a supra fuel pump with a aem fpr...i put my hi settings at -4 starting out and my low settings lean too but it runs way too lean i have no pull like i should... i dont understand, is my injectors dirty i bought my car with the injectors (they are light blue) isnt that denso 660? i would be pissed if they are not or my fuel filter needs replaced... god knows when it was replaced... im going to autozone to get a new fuel filter and hope it helps alittle, does anyone have any suggestions? thanks

Blue tops like these? Those are stock 450's, and if you're running a Big 16G, they won't be enough to let you to really flex it's muscle. Although you already seem to be aware of that.

I thought the Nippon Densos were black. Though I'm not certain about it. Got a pocketlogger or something that shows injector duty cycle?
