Installed in my DP RV with Cummins ISC 8.3
AMAZING performance increase for hill climbing and acceleration.
I also installed a pyrometer ahead of the turbo to keep tabs on exhaust temp to avoid overtemp of the turbo.
Installation was easy and I purchased an auxiliary cable to make the distance from the rear engine bay to the dash.
I only wish there was a dash label for the 4 position rotary switch. I’m looking for a third party to make one.

Rick, thank you so much for your feedback! I like the sticker idea too, might be something we need to look into for the future. Thanks!
