05 6 Speed dyno tune numbers
 

After LT headers and NPP install over winter I finally got around to a dyno tune. I didn’t have a run before putting on LT.
Mustang Power Dyno used.
Did a baseline and 3 more runs.
Ended up with 373 HP and 387 Torque.
Ive heard Mustang Dyno produces less numbers. Overall feels better and more responsive after tune.
I’m happy!
but still thinking about a cam ��

What other modifications besides long-tubes?

Forgot to add that I did put NPP exhaust on also.
