Off road isx15

[Brunolily]

Thank you soooo much for responding. We have a couple isx15 ( 2250) and couple isx15 ( 2350) year 2012-2016 . They have 400,000-650,000 miles . We’re in the middle of no where . We were just wondering if there is a procedure in de- mandating the cac, dpf, scr, def , ( everything behind the turbo) . We don’t want to change the calibration to the engine ( we live in middle of nowhere). We’ve replaced most of the turbo actuators ( the gear seizes at bout 500,000 miles, ). Like I said , we can handle the egr, egr cooler, turbo issues as they arise. Basically turn our 2015 isx into a 2005 isx . Oh, we get bout 8.1 mpg and little to none oil consumption. Service interval at 12,000 - 14,0000, thank you soooo much
