What was the torque like?

 

[Kiddo]

Could be a dodgy mafless tune?

 

[Munz]

who tuned it? has it got an aftermarket stall converter?

and definitely go 4-1's with cam and heads

 

[Not_An_Abba_Fan]

The HSV headers won't affect the dyno readout that much, just shift the torque higher in the revs and give you more top end.

Could be the tune, if the timing is wrong or the fuel delivery is out it will drop off and only make good torque down low.

Should be making at least 350

 

[tothezenith]

Yeah definitely more... as mo1st said, an average cam should net around the 350 mark.
My VY SS is putting down 339rwhp with just bolt-ons, no cam.

Maybe it's just not a happy dyno ? Plenty of them out there.
