If I may....The way the blower works you are correct it makes its peak boost up top. However based on the design of the C1 and the efficiency it creates positive pressure down low. Not a ton, but with some timing and fuel the change is enough to bring the lower end up over the OEM spec car.
I will need to pull the dyno sheets as I don't recall the exact amount it was. Bottom line is with proper programming and the positive pressure the unit has a gain across the board.

Do you have any data in regard to this?
Thanks
