Look at the pictures in the website dyno section - it's a dynojet style and not a Mustang dyno.

Something is wrong then With NO adjustments at all my first ever dyno pull with h/c/i was 283rwhp, with a simple fp adjustment that went to 299rwhp.

i was just looking at the graphs and it says the dyno was ran in 4th gear. is that the way all dynos work? or could that be why the numbers are so low?

4th gear is the gear that should be used. Something isn't right but I don't have a clue what it is. Your combo is making what my first untuned P head/stock cam/Explorer dyno made.

I say that 1 I would not take my car there other than to get my money back.

Why in hell would any tuner "TUNE" a car with a "pretty big exhasut leak".

Dude that right there is atleast 1/2 your problem.

Damn if those are standard #'s with that combo I dont even want to hit the dyno I was hoping for around 300-310 with my combo (see garage) but if thats accurate Im screwed....not even worth the cash.

What does the # matter if it's what you want? IE if your happy with it & it makes 290 instead of 300 does that automatically make the car a piece of Junk? No...just enjoy what you have, unless your looking for bragging rights...lol

nightrider50, what was your fuel pressure and timing set at after being tuned? Sorry if you already posted this info, I didn't see it.

The chassis dyno is more of a tuning tool anyway. My new motor made 581/539@the crank. Through a 5spd it should have made around 500rwhp. I put it on the chassis dyno and it only made 453rwhp But........at the track my 3300lb car went 126.66mph on my second shakedown pass. Wich by the slide rule is around 500rwhp. Soooooooo I dont really trust the chassis dyno, but thats just me.

Hit the head of the nail dead square there Mike. The dyno is a tool to be used for tuning purposes. Comparing track times\et's & spending time on the same dyno will aid refinement of what you have.
Timing & fuel pressure can be worth alot on a dyno. My base pull when I first got there was 301 rwhp. We pulled 4psi out & were rewarded with 310 rwhp. I'll be going back to the dyno here soon to finally mess with the timing; damb balancer spun before we could mess with the timing. Maybe more power, maybe not....

Fix your exhaust leak and change your oxygen sensors and have it tuned again. Check your cylinder leak down if you have access to air and a tester. That will be the best way to tell the condition of the short block.
I would surely think that your combo would stomp all over mine if tuned properly.
