I use GT5 Garage Editor 1.3.0.
In Garage Editor with my savedata loaded I open ride car tab(I had Nissan GTR selected in GT5) and put 00000A37 at Engine tune. In game I open GT mode and go straight on track (don't open garage or settings it might undo engine tuning). When you are on the track you can quit and go to car settings and check if Engine Stage 5 is installed. It gives more power and increases max rpm.
Ferrari 458 had rev limit at 11300rpm
I have only tested Ferrari 458 and Nissan GTR. Both worked.
