We recently tuned a 2013 GT500 here at Steeda Autosports whose only modifications included a 10% overdrive pulley, Kooks Long Tube header system with high flow cats, and a touch of our custom dyno tuning.
The difference? An additional 96.7 horsepower and 90.34 ft/lbs of torque at the wheels!
Needless to say, this car is now much more fun to drive! While the peak to peak torque gain is 90 ft/lbs, from 4600rpm to 6200rpm the torque difference is well over 100 ft/lbs through that particular range!
