Default Injectors

I just had my conputer tuned by pcmforless and they tuned 30 lb injectors but have not received them yet will it be okay to start the car with the stock ones if your computer is tuned for the 30 lbs just so I can check the valves?

It will run lean. Because its going to open the injector less because it thinks more fuel is following through them then there really is.

If you value your engine you won't do it.

If you like blowing things up then do it.

Think of it as a big firework. You just spent all that money to watch it go boom and say ah.

FWIW I have 30# SVO and put my stock 24 back in for a "test". No issue. I drove the car a few blocks for the "test" (needed to confirm if one or more of the 30# injector coils were bad)

to just run the motor at idle to adjust valves should not be a issue. Sustained WOT pulls..yes

If you have data loging you can see if the AF mixture is really lean but for me it was not.
