All the time! Everything just feels better in sport mode especially the steering feedback.

It appears you have to engage sportmode each time starting the vehicle is that true or am I missing something...and yes its is more responsive in sportmode.

Yes it's just like the auto start/stop, have to engage it each time the vehicle is restarted.

Always.
Might be in my head but my mpg has gotten better since I run sport all the time. I get 32.2 consistently vs 30.1.
I run all highway.
I have taken several 6 hour one way trips, and this is something i tested. I did see better mpg on a long highway trip using sport mode. i dont recall the exact numbers, but what you posted seems about right.

Better MPG when sport mode run the TB at a higher RPM? I never use it. I have a 2016 Challenger RT with it and I don't even use it with that car, very little at best.

Sport mode raises the shift points which keeps the engine higher in the rpm band which is where this little motor is the most efficient. I also get better mpg in sport mode, but only if I drive conservative (33 mpg). If I drive aggressively in sport mode my mpg drops alot (26 mpg). The higher shift points are nice, but I really like the tighter steering the most.

I think ZR2LIFE is correct, this small engine with little bitty turbo doesn't like to be lugged (RPMs held below 1500 under load). That lugging causes the turbo to work overtime, which increases fuel consumption. The higher RPM allows the engine to produce more torque without calling on boost from the turbo as much.

The 1.3 makes it's peak hp of 155 @ 5600 rpm and peak torque of 174 ft pounds @ 1600 rpm. Torque is what gets a vehicle moving and horsepower is what keeps it moving, so keeping the engine in it's "sweet spot" means running between 1600 and 5600 rpm. It's still amazing to me that this little engine makes it's peak torque at only 1600 rpm. This is why the Trailblazer seems quick despite only having a 3 cyl.

But from a stop it seems to take forever before the torque actually kicks in. While you're already moving it is very torquey.

Classic turbo lag. It's not too bad in the Trailblazer, but it's still there. Ceramic coating the turbo housing and heat wraps can reduce turbo lag, but I'm sure that would void the GM warranty, at least for anything engine related.
