Only reason I was thinking about doing the headers is because I was doing all motor. But with everything I've ended up reading on this forum, I think I'll stick with the stock headers. Seems that the stock headers are one of the best stock headers out there...

Disagree. Mustangs are all controlled by the tuners settings. If the settings change so do the numbers greatly! A dynojet just spins a drum and you click STD, SAE or uncorrected. Nothing to mess with or manipulate! SAE is the entire worlds industry standard so make sure they click that and not the others. SAE are very accurate on a DJ if you take it to the track and get your trap speed and weigh your car before hand.

I guess enough power to pass most every car you encounter plus enough to put smiles on your face.

303 HP.

With just the 3 upgrades, I was hoping it would be around 320 but I guess that was wishful thinking. I'll figure it out once I finally get the car tuned officially. It should be done before the winter months hit, so I'll be posting the numbers up once that is complete...fingers crossed

Find a shop that has a tweaked dyno so you het awesome #s that come back and dhow us the decimation.

Seriously though i'll guess 315.

To the crank or at the wheels?

On a dynojet, probably in the 295 to 305 ball park, give or take, to the tire depending on ambient conditions and correction.

guessing HP is like guessing IQ..

I know, it was just something to think about because this is my first sports car and I'm starting to understand cars little by little...
