502 Procharged mpi. Remaped ecu.MEF3 What pound are stock injectors? When you change does it richen fuel flow through entire band or just past what stock injectors would flow? In other words at the same pulse width will they flow more fuel causing the need for another reprogram? Thanks

I think the stock injectors are 36 lb/hr. If you switched to 50 lb/hr injectors without a new program you would be 39% richer everywhere so the pulse width at low speed must be shortened. Check out the Marren EFI site advertised on OSO for online calculators.
