Truck has 90 miles on it, felt really sluggish down low , and trans shifting needed a lot of love. Coming from very high HP diesels, i'm used to TQ and getting out of the hole. Stock form was unimpressive ( to me ) at best . Well, needless to say i ordered a NGauge from Gearhead who has tuned a few of my Power Strokes , and the driving experience changed massively . Throttle response and power down low is night and day , and it pulls harder up top. Now it's on to more and more mods.
