Default dyno done a few questioons

i did a dyno run today on a mustang dyno

1st run at stock with k and n filter
165.1hp @5250
171.6ft.lbs @3750

2nd run at 15psi
166.1@5250hp
207ft.lbs @3500

3rd run @17psi
182hp@54 mph
791ft.lbs@38mph


third run chart looks like detonation or lack of spark so as someone stated 15 psi is max on stock injectors



gains show 25hp at lower revs and 1 at peakbut almost 40ft.lbs at lower revs (1700-5000rpm)[?]

If you have an autostick, you can expect worse output. Also, depends on gear you run in. Lower gears yield less output, sometimes a lot less.

Finally, Dynojets are a bit optimistic. Like 10-15%. That's how the SRTs are able to make their crank rating at the wheels. Our chassis dynos (which are a brake as opposed to inertia dyno) yield about 200 hp for an 04 GT 5-spd.
