I would recommend starting spring pressures the get you lower boost levels on your system at wot
So you dont encounter an overboost situation where you go lean and hurt things.
I've used the turbosmart internal gate with manifold pressure in the past.
It can be hit or miss based on the amount of backpressure the turbo system has and what boost ranges the user wants.
Injectors are chosen based on the power your aiming for.
A very good rule of thumb is chose based on your power goals then size up adding 20%.
This will allow for a cushion.
I've posted several times about this and with the permission of the owner posted up a log showing the spool characteristics and airflow capabilities with fuel usage and included backpressure information.
I've also posted about several cars that have made their fastest passes and or best et when...
Nice build
That will require some upgrades unless you want to turn the boost down
The race gas is saving it from detonation.
As pronto said too the chip may need to be returned.
But its pretty clear its lean and I would advise not running the boost there.
