Oz Mini! Your car will be transformed. Bang for buck nothing compares to upping the boost via the reduced pulley. Your engine is in no danger of blowing up or anything like that. In fact, using the orginal maps your car will run very rich. I had a dyno's done at ALS for b4 pulley, with pulley, with pulley and ECU remap. Big difference between with / without pulley but only about 8KW or so with ECU upgrade. The ECU seems to lean the fuel mixture off a bit to give a bit more surge at the top end. However, I can't comment on the transitional throttle feel as I didn't drive the car between dyno's. Anyway the extra boost is the foundation for real HP gains. Maybe get a dyno done for b4 and after from Andrew.
