Why?

Because it does nothing to increase HP.

In a manual tanny you can wait for the engine to ramp up before engaging the clutch.
In an Autostick, you can power brake the launch.
End result, no difference thru the trap.

You are obviously an Autostick guy, push and go.

For the Manual tranny enthusiast, the synching of the engine RPMs too the selected gear is part of the ART of driving. This requires a responsive throttle. The SB provides that.

It is not a feel thingy. Going from a car with the SB to one without proves it. I've done it several times. Be happy to wipe my butt meter with your graph anytime to prove it. But unless you are a real stick guy, you would likely not even notice.

I have had my Xfire for over a year now. The throttle lag in the Xfire is still annoying. The throttle on my Dodge Cummings is more responsive. Worth $320.00 to fix? Jury is still out on that.

BTW no insult taken, no worries. it is called discussions right?
