For 2005+ Mustang GT
Tillman Speed JLT Performance Cold Air Kit and Custom Tuner package is the first essential vehicle modification for any 2005+ Mustang GT owner. Add between 25-35 rear wheel horsepower as well as dramatically increase throttle response, drive-ability and sometimes even improve fuel mileage!
With the JLT Series II Cold Air Intake Assembly, you receive 3 custom tunes for any modifications that you may have done and for various fuel octanes from 87, 89, 91, 92, 93, 94 including race fuels. The tunes are loaded onto a SCT X3 Powerflash Handheld Programmer and shipped directly to you. This device stores your factory tune, and is able to be reverted back to factory at any time!
The SCT programmer provides complete adjustability so you can adjust idle, axle gear ratio, tire revolutions per mile, rev limiter, automatic trans shift points, spark, and air fuel.
