Put down 309 @ 6174 rpm with 280-290 tq. This was on a mail order tune on a Mustang dyno. Gonna be sending the logs to NP and see if they can find any tweaks that might need to be made to the tune.
I don't fell bad though. A 6.0 cam/exhaust/M6 camaro put down 320
Sounds like a very tight dyno haha

That just don't sound right.....

I thought the same thing but everyone was dynoing much lower than they expected. A pretty sick Cobra put down 601 on a dynojet a few months ago then only put down 488 I this mustang dyno.
I know it's like comparing apples to oranges when it comes to dynos but I'm happy with it. There was a pullied/tuned 01 lightning that only put down 303.
That's less than what a stock 5.3 puts down! There's definitely something going on with that dyno!

Stock 5.3s put down way under 300 to the tire.
