DEAR SIR

how we open rpm of car GMC Sierra model 2016 by hp tuning because now in my car the rpm is till 4 i want to open till 6or 7 will you please guide me

If you want to raise the rpm limit then this can be done under the 'Fuel - Cut Off / DFCO ' menu. There will typically be a range of parameters that define the rev limit on the engine.

We usually reply within 12hrs (often sooner)
