Not too bad really. My first 400 dynoed on a dynojet was real close to the same numbers. It looks like yours could be leaned out a bit. Pretty flat line at 12 and change AFR( air fuel ratio). That's a bit fat. Mine was run at 5800 ft elevation( Reno,Nevada). It ran 297hp/360ftlbtq. Youre at 293hp/340. Pretty close. Thats pretty close to 350-360hp at the crank.
