What was the gain from stock?

I had a 04 sv8 manual was 190rwkw stock (had exhaust) made 272rwkw with 232/234 cam and ported manifold.

250 seems low but if was making 180 Syd a good gain. Does it drive good and fuel usage good? If not might be tune??

You haven’t mentioned whether you’ve had it retuned to suit the cam.

What other mods have been done? Did you degree the cam in? Use the proper valve springs? At what rpm is it making peak power?

What intake and exhaust?

How much of your exhaust did you do? May be possibly blocked or a partially collapsed cat converter.
