97 4.6L Injector Size? Reflash?

Just did a build on a buddies 97 F150 with the 4.6 SOHC.

Just made some billet fuel rails for it and I want to put in new injectors cause the original ones look like crap.

What size injectors do these things have? I want to replace them with the same size, or I could go a few # larger since I added an adjustable pressure regulator.

Also, is there anyone offering PCM/ECU reflashes for this truck? If so, I would go a bit larger on the injectors now and have the turn recalibrated for that since the truck will be supercharged shortly after its running and broken in.

Any information would be greatly appreciated... I know nothing of the aftermarket for this vehicle/engine

Thanks

the stock injectors are 19#, you can step up to 24#ers on the stock fuel pump but you'll need a custom tune to run 'em


talk to Mike @ Troyer Performance, Justin @ VMP or "groovychick" @ PHP
