What efi system is best for a 4.5 pfi cadillac engine7

[S.O.B.B.]

Loving the way this set up runs compared to the tbi set up.I'm using the torque converter from the 2.8L and not liking it that much.the stall is too hi so it feels like it's meant to rip the tires off at every acceleration from a stop.not the daily driver feel I was after but it'll do.I've made the throttle arm for the cables and I didn't check the geometry after.I don't think my TV cable is adjusted properly or the geometry is off or both. I'm on my third chip burn and have good results so far.I need to move my steering over a tad as it gets tight when hitting the gas.some more tweaks to a few things and I should be daily driving.I expect much better fuel milage because the rpm is around 2200rpm at 55mph so that will do much better.thanks for all the help of members and info on tgis site I'd say it's a success
