Currently have a catless, stage 2, 2020 Giulia Qv. I'm currently looking to do some more work too it. Any suggestions?
In all seriousness to my original post, I think stage 1 is just a tune, stage 2 is a tune and hfc/intake, and stage 3 is tune, hfc/intake/turbosstage 1-tune, exhaust, intakes. No engine modifications.
Stage 2- engine strengthening. Hybrid Turbos, added supercharger, fuel systems, pulley, intercooler etc
Stage 3. Race car.
Stage 4- EC tuned
