Hi, have a stock 351w, bolting on larger throttle body.
Background info, have a built 351w, heads, cam, intake, headers, etc. tuned no problem with stock throttle body.
Now, I am learning to tune JUST idle air, etc. with only a larger throttle body. I think will help once I do the engine swap later.
So, with specifics, looks like Throttle Body Air Flow is ITHBMA. Different bins have different values.
Currently my bin has it set at .6599121 lbs/min.
Others I see, at stock are .6699... lbs/min.
How to calculate what is needed?
Also, what other scalars, functions and tables need to updated for proper tune, with just changing out the TB?
