Review on B&M 70380 ShiftPlus: Enhancing Performance with Electronic Shift Improver by Marty Wainwright

This thing works great and is very easy to install. Two wires to the ECU clearly shown in the instructions and drill a hole and install. My Suburban now shifts much better and more confidently. I like the #1 setting better as it's a little less jerky than the #2 setting, but if you're into towing, #2 would be great. In addition, with my 96 you can switch between the settings "Off", "#1" and "#2" without any problems.
