, well, the issue is, i install the tune from the tool. it shows me 3,
1) Diablotune
2) mpg booster, or similiar i dont remeber,
3) Modify original tune
I install the first one, and it install but the vehicle (Silverado 2011, 5.3L, 6l80e tranny) is still like stock, its limited at 160km/h.
But with the version 9r27 the tune was working well. I dont know what to do.
