I think you have not driven powerful V6 cars then.
the egg and potato mercedes M112 V6 engine is simpler than the mitsi V6 yet packs way more punch. Its numbers are not liked by modders because they dont know how to understand torque bands.
e.g. you need to flog the mitsi to move, the benz literally jumps from mid revs.
Other good V6 - Nissan VQ35, the original beastly V6, has a very satisfying drive.
The 1.8 GDI in the galant is nothing more than steaming garbage, it has HPFP failures, coking of the combustion chambers, injector calibration loss and in some cases the injector driver ECU just plain goes crazy - I spent quite some money on getting proper diag tools for it, just to find out that its a useless piece of trash in Pakistan.
I promptly swapped it out for a port injected engine. Never a problem again.
