I am looking for more HP on my 2008 CRF450 already has Full FMF Titaniam System with mega bomb header. Boysen Quick shot 3 is already on the list but just trying to decide between the two main types of power valves.

From what i have found Powernow Plus claims to produce more power when both before and after carb inserts are in place then the Boysen Power Xwing. The X Wing sits along way before the carb and doent reduce intake diamerter but claims less gains in HP.
Has any body used eaither?
