Default Injector options... opinions needed

Would 28 lb/hr injectors be too much for a mostly stock L98? Or would the computer shorten the pulse width?

Since stock were 22psi, 28psi would be too large at WOT; the ECM would likely compensate at part throttle.

You could install an AFPR and lower fuel pressure but that might degenerate atomization.

A better setup is to have the stock injectors reconditioned at Cruzin Performance (link on my site) and install an AFPR so you can increase fuel pressure to match air flow increase mods.

Without an AFPR, 24lb injectors are too big. So 28lb injectors are WAY too big.

Unless you have to change your injectors for some reason, start with an AFPR with your stock injectors and go from there.
