An engineer mods Porsche 911
Here is a mechanical engineer who explains his chassis mods simply, executes them himself, and then measures their effects.
Here he is seam welding and measuring the effect A/B:
Here he is describing other chassis mods:
He should get more attention on the YouTube.

Is it misleading to say you are an engineer if you've never had an engineering job, but have a degree?

No, but it would be if he claimed professional specialty experience or employment he does not have. He said he was never employed in mechanical engineering? I didn't notice.
You find some fault with his measurements of the 911's chassis stiffness?

No. I graduate in December and wanted to know if I could call myself an engineer even though I haven't had a engineering postition yet.

When they do give you your degree, take your feet clear off the ground or load up barbell weights. Otherwise is to put your thumb on the scales.
The 1920s Briggs & Stratton Buckboard Flyer had solid axles and all chassis flex.

I was thinking the same thing. Weighting it not using yourself shouldn't have been too hard. Then you could wait out the oscillations and get a more accurate deflection.

To be fair, he apologizes profusely.

How many significant digits is an apology worth?

Aww! Everybody so hard on the poor diy guy. He said he took his feet off the floor! C'mon give the dude a break... what ecomodder is suddenly the height of precision?!. 
Congrats (a little premature) on your degree, M_a_t_t !
