Default LS 3 Injector swap

I have a boosted(Procharger DSC1)LS 3 in my 2001 Camaro. New crate engine. Tuner replaced stock injectors with LS 9 injectors. Has anyone tried this before. Car was making 621 rwhp to wheels using 80 lb. Delphi injectors with less than five pounds of boost. I am attempting to get the car up to 670 rwhp by increasing boost to 7 lbs.

Dumb ?
Why did the 80's not get used? At LS pressure, they are 94+.

Default LS 9 Injectors

The stated reason was that the spray pattern on the Delphi 80's was not suitable for an LS 3 engine. The LS 3 was a crate engine from GM and we replaced the stock injectors with the Delphi injectors. The Delphi injectors were used on my previous engine which was a LS 6 out of a Corvette.

Spray patterns are different between cathedral and rectangular heads?

To the best of my research the LS 3 has rectangular heads. Thanks for your response.

LS3 rectangular heads... always has been, production-wise anyway. My question was if spray patterns for cathedral were different than for rectangular.
Everyone reading this forum knows LS3's come with rectangular heads. Minimal research would have told you that. Loosen up a little...

Do you need LS9 injector data remapped to Gen3 format...?
