7AFE ECU, 7AFE ECU limiter Options

[Kapu]

hey i have just installed a 7AFE engine with wire harness and ecu into my toyota car. the engine is manual with gear box but the ecu i am using is an automatic ecu..i did some upgrades to this engine like porting, headers, exhaust, air intake and its working real good...however i feel the acceleration and power more when the car exceeds 4000rpm but then the ecu has a limiter at 5800rpm...is there anyway i can get rid of this limiter so that i can get to rev more...i had a few drag races already and i won some toyota levin which has a 4AGE 20Valve engine..however some cars beat me cuz they get to rev to higher rpms...is there anyone who knows what i should do to resolve this problem?
