A lot of it is smoke driven. Often a greyish haze is seen around optimal timing/fuel when fueling heavily. This gives me an idea that I am nearing max timing and will adjust from there, usually a small retard in timing cleans it up nicely.

that is very intesting.  I noticed this when I upped my max timing from 26* to 29*   I now have a slight grey haze, but a much better pulling truck in the 2800+ rpm

 

 

So what I am getting is 

 

1. Smoke telling you whats happening

2. noise

3. datalogging and resulting fuel logs

 

I find it a VERY difficult and time consuming to nail down a change I would call " progress"

 

 

as for economy, my truck seems to be easy to please.  If I stick timing between 19-20* at 65 mph I get no less than 24 mpg.  as soon as I go more than 1-2* away from that mpg drops like a stone.

That's some pretty dang good mileage!

 

When I up my main timing in the cruise section too much I get a haze and don't like it. 

 

If you're getting the haze and pulling harder it's a good timing value, but about as much as I would run without strapping it to the dyno.

I am not complaining, nor do I understand it.  

 

I will say that if other tuners in the vp44 world, including the old Quadzilla tunes, aren't blowing heads off left and right / causing major issues, then there is very little risk of causing damage on a vp truck in the 2500+ rpm area as a result of too much timing.   I dont think the vp44 can give us enough true timing at the injector to cause damage in the 2.5k rpm + area.

Yeah they haven't appeared to have too many issues in the past, but don't want to find out the hard way :-)
