LSA Injector Change - Transients

I want to keep this topic narrow in scope.

In the LSA/LS9, the stock injector (Bosch) Sprays the back of the intake valve. The injector has a unique spray angle, and I don't believe an aftermarket injector with the same spray angle is available. From what I have seen, most use Injector Dynamics injectors in various sizes.

When changing from the stock injector that sprays the back of the valve to a straight spray injector that sprays the port wall, does anyone have experience in what transient settings will help mitigate lambda fluctuation the best. If anyone has specific data for the tables, or just general concepts to share, please do.

Thanks!
