ST165 fuel pump?

I've done a 4th gen swap on my 165. When I get it in boost, it feels like its falling on its face. Not sure if the ECU is cutting out or if I'm leaning way out when the injectors open up during boost. Is the ST165 fuel pump adequate for a stock Caldina motor?

I ran with the stock ST165 fuel pump on my gen3 swap @17.5 psi for a year without issues. AFRs always looked good at WOT and I never ran into any fuel cut issues.
