Just want to hi and that I'm not a bot.
Also i here because I'm trying to get my 1999 Yukon Denali that's in ment condition back running. I've have had nothing but Vats problems. I just purchased a clone MDI2 but haven't had the time to play yet. I also have a sm2 pro tuner to play with.

If anyone has a black box tune for a vortec 5.7 Yukon Denali 4x4 please feel free to pm me.

Thanks 👍
