Installed the Banks Derringer in my 2019 L5P. Relatively simply install if you follow the directions. Had three small issues. First, had a hard time getting the TMAP sensor factory clip to release. Had to shove a small flathead screwdriver up in the slot of the connector to get it to release (poor squeeze release design in my opinion). Second was getting the Derringer wire through the grommet on the firewall going into the cab. Used two large / long flathead screwdrivers to pry back one side of the grommet and hold it open. Used a coat hanger with the Derringer wire & clip secured to the end of the coat hanger with electrical tape. Pushed it thru the firewall between the two screw drivers. The last trick was locating where the wire came thru the grommet into the cab. Don’t believe the video where it shows the guy reaching on top of the electrical junction box and pulling the wire from behind. I had to detach the electrical junction box under the dash and push it to the right so I could locate and pull the excess wire into the cab (only three nuts to unbolt). Once I saw where the wire was poking thru the firewall, glad I removed the electrical junction box, because it was located near the upper left-hand corner of the electrical junction box, where I would never have been able to reach without removing the electrical junction box.
Have not had time to drive my truck much except around town (been out of town for work). But the little I have driven it, I can already tell a significant performance difference. Most noticable is the increased throttle response. No more lag anywhere from zero to full throttle. Transmission has to relearn the shift pattern the first time in each setting, so some harder shifts were felt for the first couple takeoff shifts rotations. Shifting smoothed out quickly after those first couple stop and go’s. Currently have the Derringer in Stage 6, which is the highest sport / performance mode. Looking forward to forcing my first regen. Curious to see if I can force a mobile regen while going down the highway. Unfortunately waiting to see when the truck does it’s first regen with the iDash so I know where the GM factory setting is set at (DPF Soot Level 100% ?) Have an upcoming road trip to the gold mines in northeastern Nevada the week of the 21st. Will report more on the Derringer iDash forced regen ability after this road trip.
