Yes by tweaking the map you can add more power than just turning up the boost however just turning up the boost will grant you substantialy more power with just you pump map

Dumping in race gas will give you more power when turning up the boost, but when untuned your ecu will be dumping a lot more fuel than needed. Adjusting fuel is a start but also adding timing will really make the diff. I use to just crank the boost when i had a stock ECU and it was an "ok" gain. Now with a map tuned at 110 my car is scary fast.

you need to turn up the boost and get it leaned out, then adding just the right amount of gas to keep it safe... basically turning it into a race gas map....

But you wont make as much power as a dedicated 110 map with much more timing and a leaned out afr.

Alot of people put in way too much gas and which ends up hurting more than helping

If you talk to him again, try to talk about airflow and not boost. Some people can't connect the two.

Running more boost lower at lower RPM actually produces a flatter airflow curve. So, if the turbo can flow, say, 39 lb/min (9.8 16G) and you run a flat 21 psi boost profile, you will slowly increase flow until it peaks. If you run 26 psi down low and taper the boost toward redline you can flow more air earlier and hold it longer.

So, for example:

21 @ 3500 and 20 @ 7000
25 lb/min @ 3500 and 36 lb/min @ 7000

26 @ 3500 and 20 @ 7000
30 lb/min @ 3500 and 36 lb/min @ 7000

Which makes more power through the powerband?

well if you not tuned the car for race gas ,you actually can loose hp.
The octain number is ,how easy can your engine burn the fuel./or knock resistence/ So the 110 its much harder to burn then the 93. Just to turn the boost up ,is not enough to get the right results.
