I have a 1997 f150 with a 4.6l and i was wondering if anyone knows what the lb. rating is for the stock injectors?

More fuel does not always equate into more power. The only time you need to raise the injector size is if the injector duty cycle is over 90%. It has not been over 80% on any stock truck or car we have tuned, with the exception of one Chevy.. but it had a stopped up fuel filter.

Orange = 19lb.
19lb is supposed to be good for up to 310 hp.
