Basics...
I presume you are starting with an existing similar specced tune?
Have you altered the injector specs? Rated flow. Voltage offsets. Low pulse width adders.
Cylinder size.
Is that the 280 xfi cam?
The startup ve tables id reduce by 50 to 70%
Is there a startup injector base pulse width. I’d raise that by about 25%
Raise the idle speed to 800-1000 just to get it to idle.
Closed throttle timing 20-30 degrees.
