You would have to change out a couple chrystals inside your ECU. It will completely remove your rpm limiter. Not recommended!! People who have done it have blown their engines due to revving too high.

'14 Lincoln MXZ AWD 2.0 Turbo
'14 Nissan Pathfinder AWD SL
'05 Pontiac Vibe AWD
Also, you'll be running the risk of floating a valve at those high rpms. If your getting 'bigger' cams I can see raising the rpms a little. But on a stock 'ish' engine I agree that it wont do you any good. The easiest way to raise the rpm limiter is to go with a stand alone ecu.
