Gonna need less fuel with the bigger injectors.. and i dont think it will adjust it that much.

 

baby it, the maf will take care of the fuel trims the best it can.

 

Ok thanks guys will stock 4.8l injectors be enough for a mild built 6.0

 

You will probably need bigger injectors with a 6.0L and a cam. What you can do is drive it with the 4.8 injectors until you get to the dyno shop and change them out there - don't start it after changing the injectors until they put a tune in it to compensate for the bigger injectors - it will be very rich with the bigger injectors and could wash the rings out... Injectors are easy to change, and can be done in the parking lot before dynoing - if you can't do it, get the shop you are dynoing at to do it...
