New breakthrough or what? As far I was tracking the past couple years our PCM wont control it, does this take a special box for converting the signal or something?
I PM'd them about modding my 00 f-body file.....They let me d/l a beta hptuner 2.018 that has a tab for which tranny you have....pick 4l80 and thats supposed to be it besides the wiring harness you get from Speed-engineering or Speartech
When i pull up Quicksilverados file in the beta HPtuners, it shows it as 4l80 tranny so i assume it works

It'll be the 4L80E with a custom 9" converter, with all the fabbing needed and the crossmember he uses for f-body's, and install and tuning charges.
When I get it I'll post it. Shop is in Lauderdale.
