5000rpm ~ 7500rpm suck

[galant4g63t]

Im using manual gearbox hyper gear 4g63t td05 510cc injector (almost spec evo3)..i love the power when the boost come..but its totaly powerless when high rpm, so slow at all...is it normal at all? someone please help some advice..i waiting for wideband to tune the eprom ecu..is it ecu matter? Or hyper gear rvr is stupid spec..and evo 3 better?

Did anyone got stock hsg dyno graph? Or even a evo 3 also same problem that im facing now?

That's because of the size of the turbo... a tune will help a little. The bigger the turbo the more lag and the more power up high. Finding a happy medium between the two can be done many ways. Most common way is to put a 20g exhaust wheel on standard turbo. If your looking for bigger power, ask/look around, there's plenty of options.

I have also a dead stock manual HSGR.
Don't know what your references are for the definition of "fast". And in what gear you are.
Mine sure feels fast. It starts pulling from 3500 and feels like it hits full boost around 4500 rpm. I don't have a boost gauge.
According to the specs it should hit max power at 6000 rpm.

Maybe you have a boostleak somewhere.
Or a boostleak that only occurs under load. I've had that problem with the Ford of my parents.

Probably a restricted exhaust, maybe even a clogged cat?

Its a ecu problem...i change to evo 3 ecu and done launch control..advance abit timing and lean bit fuel on high rpm...i get all i need..its POWER..
