    I would think that you probably could get away with the higher spring pressure and then you need to do this: http://www.gearhead-efi.com/Fuel-Inj...-data-Tutorial! All VEs need to be adjusted to return BLMs of approximately 128.

    Getting ahead of myself, DO THIS prior to dialing in BLMs...if you go with the higher spring rate, I would use a fuel injector calculator like the one at Witch Hunter and calculate what your lbs-hr will be. Once you've determined that, you need to adjust that in the scalars lbs-hr.
