You don't step on the fuel delivery unless the tuning demands it. This is the point at which you need to mount up a wide-band oxygen sensor and drive it hard while somebody who knows what they are looking at watches the A/F values on the wide-band. If you're coming up lean, then it's time to plan.
\'98 ZX2 clipped air cleaner, UDP, triple note air horns, intake muffler delete, super unleaded with corn squeezins

If you ain\'t rock and roll, you\'re probably driving a Honda

the 19 lb injectors are the same size as stock but the ford racing ones have a different spray pattern some claim increased power off this mod and a peppier response. Unfortunately i can't verify since i have never this one myself. From what others  I've talked to that have done this particular mod it requires no chipping or flashing of the stock ecu. Talk to others that have done this mod is what i would recomend such as Rob from zxtuner.com for more details. He should be able to answer your questions better

Ford Racing 19lbs are not worth it. They are just more precise on there spraying patterns to each one. Some times injectors can be around 5 or more percent off. Some people like everything blue printed to be almost exact to each other.
