I also have a 2005 GT w/automatic and originally had the same mods as you do...

Got my car dynoed but because my tuner did not lock 4th gear in, my dyno numbers were also in the 250 - 260RWHP range...

You must create a tune which locks the 4th gear so you can get a true dyno number reading...

This tune is only for dynoing the car...

After you dyno it, then re-load the custom tune for street driving and drive away...

You will never know what the true numbers are until this is done because a dyno pull in 2nd gear of an automatic will not produce useable numbers...
