Custom ECU Tunes?

I’ve only tuned a couple of 5.3 Silverados. Advance timing, lean out PE, remove torque management, etc. I think Diablosport charges $75 to unlock. If they don’t list your year and engine, then it will not work.
Diablosport it much better than any of the hypertech tunes that I have seen, plus the tuner itself has more user options.

ya just from looking at there site and the options they can do on vehicles is real good, its a shame they dont make 1 for the 4.3
