Easy done but best way i found is to modify the gps so you eliminate the resistor/gear and make it a earth circuit for 6 individual wires, and put a 5.6k ohm resistor between the pink and black so it stays in 5th gear mapping
you then group the 6 wires into sets you want the same boost level in
i used 1st , not connected for wastegate pressure (usually 6 psi), 2 as e boost green or orange (cant remember which is sg2 but set to give 6 psi ) 3rd as the other wire for sg3 for 8 psi then 4, 5 and 6 as diode protected both wires for sg4 and 12 psi
12 in 4th on std wheelbase will open your eyes and you may choose to group it with 3rd
if your dragging with long wheelbase you can take bigger steps , as you want as much power down as early as possible
something like 6 , 15, 25 30 if your setup for it
or there are time based and sequential options that may suit you better in EB2
