Have just finished putting engine back together and it runs on idle perfect but as soon as I go under load it holds back misfires?? I have fitted a decat pipe and equal length manifold and wonder is this causing the issue?? Help lol

Is there way to test without buying new just on a hunch??? I have thought its got to be a air fuel spark issue or a vacuum leak but gettin to the end of my wick today with it!
