Hey, firstly in this alfa probably the boost isnt controlled by ecu so You dont have to touch boost maps. The maps I ve found in your ori file:
79704 EGR map
79AE2 turbo limiter by temperature
7B148 Driver wish
7B232 starting IQ
7B4AE Torque limiter
7B51C Smoke Limiter
7BA84 IQ Limiter by temperature
7BB94 Rail pressure
7C100 Rail Pressure limiter
7C328 Rail Precontrol Valve Duty
7C6AC, 7C8F4 Duration Maps
7D956, 7DB56 SOI maps( Rail and SOI axises are between IQ Limiter by temperature map and Rail pressure map)
7E286 Rail pressure limiter by Temperature
7EFE2 Turbo pressure map
7F38C Turbo limiter by atmosferic pressure
7F518 Turbo control valve duty
7ED9E SVBL
I hope those maps are identified correctly. SVRLs Im not sure about their locations. I m interested also into SOI limiter maps.

Smoke map:
factor: 0.01 that gives you injected quantity in mm3
X axis which is mass air flow has factor 0.1, unit is mg/stroke
Y axis rpm has factor 1
After You do the tune write us the effects ;)

oh ive thinked that is in afr or lambda like the other alfas, i did the tune with 25% more duration because the owner have a golf with bigger nozzles and want smoke on the alfa :wtf: , its impressive with that duration
