You want to know who much HP you are making?

Just log MAF and RPM and you can get many points. Pop those points into excel and you get can get a graph of HP. To get torque you use TQ(ft-lbs)=HP*5252/RPM. Right now all I have is an OBD scanner taking logs of the car.

This is the software package I am looking at right now:http://www.hptuners.com/order.php
It is $499 to tune 2 cars.

I'm not sure what it takes to get the software that allows you into the PCM. My understanding is that its proprietory and you have to buy the license. I don't know anything about what it takes to tune a Subaru...
Our tuners allow us some basic adjustments... spark, timing... but the fuel mapping and other stuff is basically hands-off.

This is what use to tune subarus:http://www.romraider.com/
It is open source and the cost to start was buy an $80 cable to tune an unlimited number of cars. It is a shame it won't work on the fords.

I see a lot of dyno sheets around here. We all know that a dyno can read what ever the operator wants it to. I don't see very many logs of MAF. Logging MAF will tell you close to what your CHP is. I just got a reading of 233Gm/sec out of my '05. As far as I know the car is stock. You can estimate the CHP with this formula: 1.31*Gm/sec=CHP, of course this depends on how accurate your MAF scaling is. My stock '05 comes out to 305CHP.
Ohh I have another question. Why is there not more people tuning thier own car? I come from a subaru and there are a ton of people tuning the cars on thier own. I have been tuning for years and I am amazed that there is not more mustang owners doing thier own tuning.

(Just a joke man... that's a really nice time. STI I presume?)

Looks like you have some ground to make up to get back to the level of your Subaru. Get to modding that thing!

What is 233gm? Is that the same as MAF counts?
This gauge records MAF counts and lbs. per minute. It also records crank horsepower, probably using a similar formula.
I have free software to tune my motorcycle. Even if there was free software to tune my mustang, I wouldn't do it. There really isn't much need for it, like someone else said.
