Evo IX bogs down under load

random issue. The car was sitting for a while and gas tank was low. I put some gas in the car and took the car out and after it was warmed up I boosted the car and it spooled up and then all of the sudden bogged down and felt like it was going to stall. So I thought maybe something on the fuel pump filter got stuck. I pulled the fuel pump and replaced it as well as a new filter. Buttoned everything back up and the same issue. I thought maybe a boost leak .. Did a boost leak test no leaks. My only other thought is a clogged injector/s . anyone else has any thoughts.

I checked the plugs and they looked okay. I will swap them out and see if that helps.

Catless. No smell no abnormal color smoke out the muffler. As soon as I get on the gas it bogs right out and SES will flash. I should probably scan it to see if I am getting any codes.
