Software flash from Monsoon 410 to 450

Recommended Posts

Just read the Monsoon 410 and 450 are identical.  450 gets higher torque and HP with a simple software flash.  Then a new engine cover.  True?  If so, how without paying $7500???  Worth it?  (2018 23 LSV).

You could change the HP output of your engine by changing the max RPM.  They probably also mess with timing to get a little more torque at the top end, but basically that would do it. 

Power = Torque * RPM.

This is the same for cars like Audi, they have the same base 4.0L V8 that is used in the S7, RS7 and R8 but the performance specs are very different. There are aftermarket ECM upgrade kits that can improve performance.  While the 410 and the 450 use the same blocks my bet is there are more differences than just the ECM programming.
