Fuel Cut After Installing New Pump

Hey there. I recently replaced my fuel pump. I was running a walbro 255 but then I decided to replace it with a bigger pump. I bought a Quantum Flex Fuel 340lph pump. I read they were good pumps and they were local from Ventura CA. Anyway, I started to get fuel cut when i hit the gas hard. Do i need to get it tuned in order to get rid of the fuel cut? Any ideas? Thanks.

I don't know about fuel cut, but it isn't uncommon to need at least a touch up on your tune after installing a larger pump.

Ok. I was assuming fuel cut because it stutters between 3k and 5k.
