I prefer the idea of cutting the injector power because once you do, the only fuel going in is whatever is already in the manifold--so you'll only get a couple of revs more with any fuel at all, really.
My "other car" has a spark-cut rev limiter, and if you ride the limiter you can load up the exhaust with fuel and then ignite it in the header. Thank heaven for low-restriction mufflers....

We (friends and I) used to intentionally cut spark to engines while they were at high RPM/load, then cut the spark back on at full throttle as they were about to stall...
think: flame thrower kit.
