I run into this alot too where I find that the rig has had a Pyro probe in it the tell tale sign that its had a tuner in it. you never know what was done to a used rig before you got it. I have seen some pretty beat on dodges fords and chevy's.
LLY: LLY max pulsewidth?

6 speeds can take alot more abuse before limping. i normally put them up to 2200 without issues so far.
On a 6 speed yep. gave that to a guy on a LMM once. he said "Oh I won't use the hot tune" But he wanted maxx effort! two weeks later he was in for a new convertor. lol. then he sold it lol.
I've only seen some PPE LB7 tunes, but they ran ALOT of pulsewidth, but not alot of timing.
Now, pardon my unknown here, but is it the same rule of thumb as gassers, more boost, more fuel and less timing is safer than pushing timing?
they will make 31*@3100 rpm on the 310 and 350 tunes. just plus width varies between the two IIRC. I think the lb7 350 tune is in the neighborhood of 3300uS
Nope cause timing here is not the same as gasser timing. Too less timing means high egt's, too much and cyl pressures jump to where you can kill Pistons or rods.
We are not timing spark to ignite. We are timing the beginning of the injection of fuel and need to concidered at what point fuel is being sprayed before and after tdc.
