Getting 320bhp and 280lbs/ft torque from my MY01 WRX wagon but got slight fuel starvation/detting at top end on dyno run. During road test/mapping session no problems noted. Mapped on optimax but ran BP ultimate on dyno run.

I trust the tuner and they have a great reputation.

Can anyone help, as I am doing a track day soon so I'm starting to wonder if she's gonna blow...

Should I....

1.Fit a fuel pressure regulator and/or aquamist system.
2.Just re-map to dump more fuel in & pull back to 300bhp.
3.Not worry becuase a dyno run is different/more extreme than real world/track conditions.

Cheers

Running:
IHI VF30
STi7 Injectors/intercooler/scoop
Upgraded fuel pump
Full de-cat system
Ecutek re-map etc.

Are you monitoring det with a knocklink? this could be what you need, when you start to det, back off.

This would probably be a cheap and efficient solution depending on how much you trust the old knocklink.

Otherwise you could get it re-mapped on an RR and not worry about such things, still a knocklink seems to be recomended by the people in the know.

Speak to the mapper. You'd be best checking the top end fuelling is not lean before hammering it on a track.

Some rollers with inadequate cooling make cars det when they never would on the road or even track.
