the torque did seem softer down low, but I never had software to match like Discovery sells. It seems to rev quicker.
I took them off before I ended up doing cams and the differential, and never got around to reinstalling them.
They would probably work good with tune to go with or if the car had other mods or even cams to help it breath at higher rpms.
