Holley Terminator EFI System - LS

$2,050.00 $3,166.95

We've tested this unit and it work great.  If you're not comfortable with laptop programming, the included handheld touchscreen did an excellent job all alone.  The free Holley desktop software is easy to use and can provide some additional fine detail tuning tweaks if you're comfortable using a computer.  At a minimum, you can use an SD card to move and view all your driving data from the handheld to a computer for better performance visibility.  ** HIGHLY RECOMMENDED **
