looking at the plate kit for the nitrous express kit and they hav a link to the mustang enthusiast addition that says without a tune it made 357.85 hp with a 100 shot then with a tune it made 449.31 hp with the same 100 shot. Is this possible?? is there anyone who has a tune and is running this same 100 shot set up?? that seems to be a big gain for just a tune. they said they used the Sniper tuning software.
