[Bloodseeker9889]

heeey

i have 2012 gmc sierra regular cab 5.3. i tried to do a custom tune by hptuner but i couldn't because there is a security feature in the new 2012 gm computer.

so, which is the best diablosport tuner device for my truck?
because am new in here
in the feature can i buy a custome file to my truck?

the diablosport Trinity will work perfectly for your truck... and I have a special package deal for it plus custom tuning at a reduced cost so you'd save some $$...
