First, list the codes so we can see them. Also, try to erase the continuous memory codes. They can sometimes stick around from a previous installation.

I run an A9M on 351W and it is sometimes a bit hard starting when it is hot. I have recently adjusted the idle screw on the throttle body so that the butterfly is more open when the pedal is at rest. That has helped the hard start a lot.

Does it act like it is having a hard time cranking when it is hot? That can indicate a base timing problem.
