Need help tuning my calibration on a 0411 with road runner emulator using TunerCat.

Hi
I only program LT1’s but have used TC in the past.
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.

I am making the assumption that he is starting with the 5.7 Express van 0411 file. If so many of the settings should already be correct for the base setup. Engine size, Injector size, Injector compensations, etc.

I am attaching an Open Office file with some values of the key tables I was talking about as well as a VE table that should be a fair bit closer than the OEM GM Van table.
