Currently running a sct live wire with gearhead extreme street tune. Laid down a 8.34 in the 1/8 track few nights ago. Got a good deal on a spartan tuner and am trying to figure out if im going to get more power with spartan before i pay the 250 relicence fee. Will be selling one of these tuners just trying to figure out witch is going to be best on my truck. Any help would be greatly appreciated.
