Same numbers and mods as I have in my sig i put down 25rwhp less on a mustang dyno. They put the car under load and the dynojet doesnt. Good for tuning, not so good for numbers. So its a combo of your weak exhaust and numbers from a mustang dyno.

Ok i still dont know what to do with this car. Not only did it have a weak dyno pull, but over the summer the best i ran at the track was a 13.9 and the thing has been getting progressively worse gas mileage (160 to a tank). But it seams to run fine, idle great and when i pulled it on the dyno the hp line kept climbing and and the tq curve was a nice even line just low.

mechanical problems
converter going out
trans slipping
valve springs
wrong push rods
bad bearing, water pump,alt, ps
fuel reg/pump
ignition problem?
what have you checked so far....things don't just bolt together and work well
its a system, everything has to be in top shap for the sytem/car to run right
With your mods and a o.k. converter I would say 325 rwhp would be a resonable goal
Just my opinion, but i'm no genius

trans is new,valve springs are new,pushrods new hardened from combination motor sports, new plugs wires cap & rotor, coil, (if there was a ignition wouldnt the hp fall of at high rpm?)

it sounds like the combo is on the car needs an af ratio check during the run. i would say you have a different problem than not enough parts. the parts you have on are not killing it. run a scan tool on it and watch the fuel trim numbers and get the fuel pressure. the low mpg says something and so does the hp numbers.
mdacton may be right.. seen fuel filter cause great torque numbers but die at high rpm. start with the basics before you change anything
