Excessive regens leading to delete... what to expect???
So here's where I'm at... my '11 LML (93k mile) gets horrible mileage (11-12 ave) and regens <200 miles. From my research, I'm finding it could be a bad 9th injector, the DPF is going bad, the pressure sensor is bad, or the injectors are "leaking" causing more soot. Regardless, no codes are thrown and no other issues are apparent. Lots of reason are leading me to head down the path of driving down that extremely bumpy road until all that emissions stuff falls off...
That being said, what are all your experiences after deleting that had similar situations? One of my main concerns is if it is an injector issue causing the excessive regens, and they are dumping more fuel than needed, than regardless of what "clean" tune I get, I could end up blowing a lot of black smoke, which is not what I'm after... I want engine reliability and longevity, plain and simple!
(See sig for current upgrades... next upgrade would be WcFab Y-bridge Kit if the EGR happens to fall off that bumpy back road)
Thanks for your input!
