It seems a little laggier then 70mm, but not much, once it lights it builds boost fast. With 60lb injectors and the 78, I was at about 72% duty cycle at 15lbs, now it's at 78% duty cycle, but im also at 17-18lbs in 3rd. So spool like a 70, and pulls as hard as 78 up top. I won't know until I get to the track, but feels strong. Both the 70 and 78 made 8lbs of boost on the 2 step at 3500, the 66 makes 11.2 lol.
