2015 Sierra programmer

Kman731 · August 9, 2020

Hey I'm brand new on here, and just bought my 2015 Sierra

I was looking for an AFM delete, but I'm thinking of buying a programmer instead... I've never owned a programmer, so forgive me if this is stupid. I want:

-AFM delete

-General performance tuning

-Speedometer calibration

-LED lighting conversion? (Do you need to reprogram anything to not throw errors when you switch from halogen to LED?)

Is there a programmer yall suggest?

Thanks

I have no idea about the LED lights stuff.

As for tuning there are several options. There is the hypertech tuner, the Diablo tuner and a lot of people use BlackBear Performance on here. The guys at BB do more a custom job as you work with them to tune your truck and not just plug and play some pre-made tune that you hope you like.

There are probably others out there too but those come to mind. Past that you get into HP Tuners which I use that is complete custom tune that is done by yourself and takes a long time to learn.

welcome to the rabbit hole...lol I think for body computer and lights mods there is a guy called whitemedia he can modify radio and chassis puters'. then there is also the vxdiagnosis, whic isnt a tuner but a handy tool to add to the collection , lets you install GM upgrade or down grade files into the various onboard control systems, best to use with gm subscription
