custom tune

I had a custom tune done for my Silverado. I used BlackBear performance. I am VERY happy with their work.

I can tell you that 99.9% of all dealers know nothing about custom tuning. In fact, most want to flash the chip when you go in for maintenance...Be careful.

My advice is to find a group like FABO for your vehicle (or for the computer in your vehicle) and see who they use for custom tuning. Also, a custom tune will always be able to access more parameters than a hand held tuner.

I hope this helps.

Thanks,
