Every dyno is different so take it to the track and you can get a better idea of how you compare.
Besides mustang dynos read low anyway.

That's about right. Green's really don't 400whp like everyone posts (or at least I've never seen one first hand).

They are pretty much a (solid) 350whp turbo and should make that on most "accurate" dynos.

on race gas you'll hit 400whp...but 350whp is what I would aim for on pump gas...thats still a bit on the high side usually 330whp on ours. DD Dyno...The "real heart breaker"

Well, you can't just look at peak #'s and call it a day. Consider the shape of the curve- larger snails tend to make power all the way to red line versus the stocker that dies off in the upper-rpm range.

If your CEL is flashing, then you need to go back to your tuner and tell them that your motor is knocking. This is bad and should be fixed right away. Stop flooring the car.

Maybe the tune is fine but you've just got a tank of bad gas. I'll get those a few times a year.

As for your numbers, i wouldn't worry about it too much. Take your car to the track and see what it traps. On a dyno jet last year with my stage 4 setup, i made 200whp, but then trapped a 104mph at the strip. So obviously the dyno was low reading but still tuned well. Dyno #'s don't mean much IMO.

thats bull****.... take it back to your tuner and get a retune... a good map should not knock... if a bad tank of gas is causing it to knock its tuned to the edge. Try putting some colder plugs in it and see if that helps...

If it were me, id take it back to the tuner and get it retuned though and if your knocking at full boost, the last thing your going to need to do is take it to the drag strip, your car will start pulling timing the second it knocks and you woulnt get a good time anyways...

here is my dyno sheet:



yeah i stopped flooring the car right afterwards when i saw the check engine flashed. after your car gets off the dyno you're going to want to of course test it out and floor it. that was the only time though.

yeah, for some reason i was hoping for 375-400 cause that was what the shop would tell me so i was a little disappointed in 345. but now that i see other dyno sheets, thats about average. as for now i am just throwing in a bottle of octane booster each full tank to be on the safe side.

Different dyno and slightly different setup. Although the bases are there (257/Green/850s). I made 340/340. So you sound about right to me. How do you like that greddy fmic? I hear mixed reviews on it.

the greddy fmic is fine, i sort of dont like the way it looks on a 06 front end because of how it has the bigger mouth then 04-05's.

something is going on with the timing curve. There is a pretty major dip in the midrange. Might be knock correction. Might be the timing curve. Might be the AVCS mapping. Hard to say. The peak power is not bad.

Does the Cobb Street tuner software adjust the AVCS curve also??

or which systems will tune the AVCS?

thanks Clark!

Yes. Cobb street and pro tuner software will adjust the AVCS maps. Most tuners do not adjust them however. I have no idea on this car in this thread. I just noticed that power is dipping down and back up around 5000 rpm.
