what will i need to do to my ecm to run 50# or 55# injectors

[turbo9]

i am running stock injectors now and would like to jump up to a 50 or 55# injector, what if anything will i need to do to my ecm?

Nothing for 50s! They will work great. Other things to get, Red A XP pump and matching chip for the 50s, hot wire, volt blaster, adjustable fuel regulator. Then you'll have fun

55's and larger need a low-impedance injector driver in the ECM. Many companies offer this upgrade for $100-$150. The MSD 50lb. injector will work with an unmodified ECM. Just make sure you have the chips and all other supporting hardware as mentioned above.
