Picked up an Impreza wagon about 3 months ago - had been looking at GC8s but needed something a little more tolerant of the poor quality (95ron) fuel in these parts so ended up with a GG wrx instead...
Tried to run on 95ron for some time, but it really needs tune for it. stock its tuned to 95/98 but runs way better on ron98, much smoother...
For every other fuel you need tuning on GC8 before it will run smoothly.

I the meantime i have fitted a TD05 turbo because i got one offered cheap, difference is very big but the ECU is not really happy about it.
Need to step off the gas a bit or just try to keep the Turbo pressure under 0.9bar, when full throttle it goes to ~1.5bar after goes steady on 1.1bar which is a little too much for the EJ205 block.
Still need to test it on Dyno
, first ECU

Yea, exact same problem here. after i drive out of the street i got the remote control in my hands
Also very handy in parking garages where the exhaust sounds like thunder and back-fire sounds like C4 dynamite, fun when empty but not when surrounded by 1000 people and get stopped after every 5 meters because they want you to smell their fear...

The exhaust is controlled by a remote control, looks like a door control.
My exhaust, the Raceland, has 4 different stages. Closed, Closed-Half, Half-Open and Open.
Got mine often on Closed-Half, same sound as open but way more silenced, just enough to get the sound but be able to drive around in streets and parking garages.
The Varex can be adjusted to whatever needs, cool, but downside is you can never get it to close just enough to get the loudness you want 2 times in a row.
The image below shows the system, the yallow/red connector goes to the exhaust through the trunk.
