Hi Steve
APS in Frankston tuned it, as recommended by Rob Herrod.
Runs 98, but we went for a 3' upper pulley which lowered the boost down from about 18/19lbs (with the 2.75' upper) to 14-odd just for a little more margin of error, especially when the ambient air temp is hot.
Whatever FI you go with, consider using an intercooled setup, it's important for lowering the intake air temps, which is critical to prevent detonation.
A lot of people run Procharger setups (or similar) in the US, great for initial torque but flattens out a little at the top end. Tuning experience is critical, as is the tuners ability to access the right tools/software/tuner.
