I just picked up hptuners and tinkered just fine with my tbss. I plugged it into my 07 Tb lt inline 6 to pull the map to look at the stock tune to do alittle work on, but the tune won't pull it says 90mins to download and says lost high speed. At this point and time I am confused because I don't want to burn this vcm up. Any ideas what it could be? The scanner will log just fine
Uncheck the high speed box and try again.
2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.
If you don't post your tune and logs when you have questions you aren't helping yourself.
Also, what version of software are you using?
We got this guy Not Sure, ...
I'm using the newest software, I downloaded the "try it out" program and it was the more recent version than what I got in the package. I'll try in checking the high speed box. Thanks!
