4.6l 2v stock injector type

hi for my 1998 GT with a 4.6l 2V what type of injectors are stock? I got 125k on the originals and am pinging at wot mid rpms.

Want to by a new set and want to make sure I get the right type of connector and psi.

19lbs EV1 Jetronic. You can switch to the EV6 24lbs USCAR if you want, but you will need the USCAR to Jetronic adapters.

If I switch over to the 24lb will I need to re-tune? Or will the car auto map it?

Technically yes, but the 02 sensors should be able to compensate for the added fuel. I ran 5 24lbs injectors and 3 19lbs injectors in my 4V swapped GT. Ran fine lol.

24s are a bit much for a NPI. My 03 GT had full bolt-ons and I put 24s in and tuned it for them and she ran rich as EFF man. I even checked it on a scan tool to see how much fuel it was pulling and it was maxed out on how much it could pull out.
