Could be that the GT45 spools faster. I don't have any old logs from when I had mine. The 7875 just feels like it spools faster based on the seat-of-the-pants meter. I don't have any logs of me smashing the gas pedal since that's usually a waste of tires on the street but it does go into positive boost around 4k rpm when I ease into the throttle. The converter stalls to 3500.
