Anybody know what the standard deviation is on a dyno? If it is greater than 1%, theoretically there would be no increase in whp??
I replaced mine with the Greens.
I think,that with the Catback exhaust and the filters,the car does seem more sharp,especially @ higher speeds.
But that might be a mental thing too
My question is why it comes out plotted in excel wth so few data points. this doesn't look like most dyno charts i see.
