You are nearly there mate , as to starting its just a slow methodical series of checks one by one ,air, fuel,ignition,timing ,wiring - as you had not even a hint of the engine firing on any cylinder -it should be a bit easier
Once started - it will - before mapping to big power- check again,and again ,throttle opening ,leaks,all voltages correct where it should be ,all air systems opening closing and leaks .
A couple of leaking clamps or drips can ruin your dyno time and spoil your day ,usually its one of those DOH moments!
Once done and running well ,you can then alter a few things to give small improvements such as flow straighteners at the bends in pipework and reduce the 90 degree bends ,add oil to the charger rotors,get pressure drops and temps ,and adjust the boost etc
So far you have done a great job!
