Slight misfire under load

Hi guys I'm getting a slight misfire for a second or so under load. When u put your foot to the floor it pull to 5psi has a slight misfire then continues to pull all the way through any ideas?

 

Injectors wise I only had them fitted at the start on December at rs tuning so would u start with new fuel pump? What about coil pack could it be a pos?

 

Ok cool if you could have a look at it lemon that would be fantastic when ever your free

 

Yup was the map in the end so that's all sorted now. just this small problem to fix :-)
