I'd suggest that you take it to another dyno.

Did you get it tuned at the dyno?? Even if you did those are hard to believe. My bro's z06 with a tune only pulled that exact number but on an A4 mmmmm.....take it to another dyno, not a mustang dyno though.

Dyno's can lie. I have runs on two different dynos with the same tune. First run 413 hp/395 torque. Second run 398hp/377 torque. I believed the second run much more as those were SAE corrected numbers. Personally, I'd rather work off a stingy dyno. You're much more likely to get real results.

Just don't see how the car can be making that much power with the mods you listed. If it is, you've got one strong running C5.

either the numbers are not corrected or the trans didnt stay in 3rd gear. dynos are only to be used as a tuning tool......so take the numbers shown with a grain of salt. they dont matter. the only numbers that matter are the numbers it runs in the 1320

Try this
Try to get your car weighed in the same conditions that you run at the track. Give us the track conditions (altitude, temp, humidity and barometric pressure). Then let us know what your trap speeds are, and then we can let you know what you rwhp is closer then that dyno. Trap speeds and weight is a very good indicator of your true rwhp.
Have fun at the track,

Live axle is a term for a type of beam axle suspension system that uses axle shafts to transmit power from the differential together as a unit through a limited slip, or one drive wheel through an open differential.
A live axle consists of a central differential in a single axle housing that also contains the axleshafts that connect the differential to the driven wheels. The differential is connected to the engine via a universal joint to the driveshaft, and then through the transmission.
Live rear axles show less drivetrain loss in the F-Body cars due to a more direct connection to the drive wheels than the IRS unit has through the articulated half-shaft system. Generally also live axles can be built stronger than an IRS (not the stock F-Body 10 bolt though!) and are common swaps for high horsepower IRS cars (Corvettes and Cobras are examples).
The detriment is that a live axle housing is a static connection between the two wheels it drives, and can be adverse to handling characteristics since those wheels are connected in side to side sway and angular motion...

This is an update on my previous emails regarding the dyno day at Horsepower Connection.
This is a first come first served basis. The first one on the dyno will be @9am, and they will go in order from there. They will close down after all the cars have been run, so my suggestion is to show up earlier than later. Please email me to get your name on the list.
Discounted rate is $50 for 3 pulls on the dyno (normally $75+).
The confirmed dyno date is for Saturday, 11/8 at:
Horsepower Connection
3939 12th Ave SE Lacey, WA 98503-2245
You can get directions at www.mapquest.com
I hope to see you there!

Email me right away if you have not yet confirmed your attendance for the Dyno Day. Also, if you can not make the 8th, but still want to do it, let me know, as I am composing a possible list for the 15th. notdads@hotmail.com
Let me know if you have any other questions!
