With this box you can pull at any ramp rate you want..... I have my dist locked at 40 deg, I have the timing curve set up so it has 22 at idle and advances from 22 to 40 from 1000 rpm to 2 000 rpm..... My boost curve doesn't actually pull any timing until 4 lbs and then takes a total of 20 deg out by 12.5 lbs..... So that leaves me with 20 total when it is at full boost.....

But like I said you can do basically anything you want with the timing and boost curves in this thing.....
