October 15, 2007Bigger injectors without the motor work to support them will give you no benefits whatsoever!!! Just troubles.
October 15, 2007what kind of motor work are we talking. a full out rebuild or new heads and valves
October 16, 2007Your original question depends on several factors. First, what size injectors do you plan on using? What mods do you currently, or plan to have in the near future? Also, remember to have your maf and injectors done at the same time, as they are calibrated to each other. It does no good to have more gas available, if your truck doesnt know it has more air and can provide that extra fuel. As far as bumping up the fuel pump, that again, depends on how big you plan to go.
