Is the place that tuned my 6.0 Sierra.
2 mpg gain driving 80 miles a day hand calulated.
Thats 50 miles more each tank.
200 miles additional per month.
Firmer, later shift points.
Hp gain ? Unless its dynoed it a guess to actual gain.
I have my stock ecm if you'd like to purchase it so you can send it in to be tuned that way you can keep your oem ecm.
And better yet you dont have to wait days while you send yours in to be tuned and sent back.
Pm me if your interested.
