I’d look into a Pro-M EFI, no need to pay a tuner a dime and you can change your combo 100 times and never need to re-tune the car.

Fuel pump is fine, check an injector calculator timing is 10* and fuel pressure is 39-40psi with the vacuum line disconnected.

Injectors will be near their peak. 325-350HP. I would keep them.
