Electric ratio adapter

[Joseraya]

Has any one used or installed a ERA in your truck gear ratio changed from 3.42 to 3.73 and I'm getting abs and brake lights come on

You need to change your ratio with a tuner. I used an intune when I went from a 3.08 to 3.73. Oddly though I didn't get any warnings when I changed mine like I've read would happen. Drove for a few days without the change before going for a dealer visit (under warranty). Only diff I had was going 15 mph faster that I really was.

Blackbear performance tuned my ecm and tcm I emailed blackbear and they told me it was in the ebcm. I bought a ERA and need some info where to install it. The company I bought it has very bad customer service and there close all this week.
