2005 Mustang GT w/ NX 125 shot
The NA trim includes a stock 281 3v motor and 5 speed automatic tranny with a JLT short ram intake, Jet throttle body spacer and Hooker long tube headers. The Mustang Dyno reveals 289 hp and 294 ft/lbs at the peaks.
The NA tune was retained and the knock sensor sensitivity was increased to act like an electronic retard box. The nitrous dyno runs were done with about 4 gallons of Sunoco GT Plus 104 Octane on top of the remaining 2 gallons of Unocal 76 91 Octane in the tank. The results were amazing and the 125 shot definitely was advertised for the rear wheels. 377 rwhp and 445 ft/lbs at the peaks with a 3500 rpm trigger. When I visit my local drag strip I will be backing the trigger down to 3000 rpm, I expect nearly 490 ft/lbs immediately after activation.

Man hit the track, I want to see how that sucker runs!! What tires you going to be on?
Keep in mind, the dyno will almost always show a torque curve like that for an automatic. It gets worse with a higher stall speed converter.
