Yeah, I think I understand now. So my plan of action now shall be as follows:
Leave the engine alone, no point in spending on upgrades that do nothing, rather spend it on :
1. Decend suspension, B12's or Street-S kit, adjustable hieght, damping etc.
2. Eibach ARB kit
3. New brake pads and braided hoses, maybe new discs, depending.
4. 4 new tyres, either the same pirelli PZero's or F1 Assyms.
5. Raggazon backbox, just for the sound
6. Some eyecandy upgrades.
7. Full service, new timing belt, sparks, Q2 install.
Basically, leave the Alfa as is, upgrade suspension, brakes and looks.
After my TB clean and ecu reset, the Alfa is a new beast, it somehow found more torque, or maybe it is the "learning throttle" because all of a sudden I have more power at my toetips when I need it, it revs better at lower range, sounds better and pulls a hell of a lot better throughout the rev range, recommend for anyone.
I would love to supercharge the Alfa but I doubt I'd spend that much for a small vacuum cleaner at my inlets and I doubt anyone here has the knowledge to install it proper. In a perfect world small upgrades like supercharge or turbocharge shouldn't costs more than a small tract of land but hey, that's the world we live in. I might still look into NOS system, seems cheaper but again, knowhow is non-existent so I won't even bother. The GT is a naturally flippin fast car already, especially since my ecu reset and TB clean, I literally have to hold on to the steering wheel as I am pressed into the seat. Loving it
and the ladies LOVE the Alfa already as is.
