Simple math.
370 x .73 = 270

So your new injectors are 27% (1-.73=.27 or 27%) larger then your stockers, take out 27% fuel on low throttle map to get it to idle.

-27 across the board on low throttle pretty much

Then just get a wideband or get on a dyno and tune the high throttle map, set decel air function, etc. etc.

Everybodies settings are going to be different.

I also forget the MAF correction but you can probably find that in a second.
