I would not worry to much about dyno #s. How is car running? How does it feel on WOT? It sounds to me that your expectations were not met. What dyno is this anyway? Dynos differ with their #s.

I don't think your numbers sound too far off based on your mod list. I agree with Proud Owner, how does the car drive and feel? You can always get another test on a different dyno and chase a number if that is what you're after. If you are happy with how it feels, enjoy it!

Stick or auto? Those numbers don't sound too bad, if you're an auto I don't think they're bad at all.

What's more important is what were the baseline run numbers? The dyno is more a tuning tool, then a means for determining how much power you are generating or how fast your car will be. Also, what about power/torque under the curve?

Need to overlay the baseline over the final to see the overall improvements in the curve including peak.

Also, which dyno was used? Mustang Dyno/load bearing type are stingier than inertia type.

I would estimate 335/350 for a stock setup.

6 speed, the car feels great, was just wondering if these numbers sounded correct for the mods.

looks like you picked up ~90-100 rwhp over stock which is pretty good.

What kind of dyno? A million things factor into dyno numbers, such as what transmission, DA, correction factor etc....Like everybody else said, you should compare them to whatever base figure you might have. Bottom line, all that matters is how she runs and what kind of times she is able to lay down.
