Well, if theres no check engine lights I would guess you need to get some health checks done, compression and leakdown test. miles?

All dyno's have variances. I wouldn't expect an '04 (490hp) to put down 440-460whp without significant mods or a very generous dyno.

Fo a compression check dry and then with oil squirted in the cylinder. Some blow-by is "normal" on the pre-LP.

That said, I'd expect 390-400whp from a stock one.

I have 36k their was no check light but they ran a scan on it showing o2

As soon as my maintenance is done I will run it again on the dyno hopefully I can gain more power.
Fabspeed ecu- catdelete- intake - Exhaust
I already have

ive dynod a few pre Lps and they range 360-380.

You would think they would be higher.
They are really just art on wheels

That's the weird thing I do have mods exhaust and intake and ecu tune from fabspeed and cat delete.

I am not sure if any of those adds meaningful power. The car is naturally aspirated.

The dyno figure sounds about right to me.

Sadly I think that’s right. I’ve seen a few others right around that mark. 490ish crank gets beaten down pretty hard by the AWD system. If you do a RWD conversion that 365whp will jump to probably 410-420whp. The good news is the car is light so power to weight wise, 365awhp is honestly pretty substantial. Not a rocket but you get the point lol.
