Hi friends -- I've searched this ad nauseum, and am coming up with more questions than I am answers. Regarding non-delete tunes: do either the Kerma or Malone tunes actually lessen soot load (or otherwise allow the DPF to thrive more so than with the stock "fix" tune)? Specifically, I'm looking at tuning a 2011 JSW 6MT.
I ask this because I'd like to do a non-delete tune initially, and once my Dieselgate warranty runs out I'd consider going full delete. Malone will sell a tune loader with both tunes, so I'd have the "full delete" tune at the ready when the time comes. That said, a member here has reported impressive DPF results with a Kerma tune -- he sees longer intervals between active regens, and sees more effective passive regens when on the highway as well. That seems to suggest that the Kerma tune is far more DPF-friendly.
I emailed Malone to ask whether a byproduct of their tunes might be less soot (or anything else that would benefit the DPF), and I must have worded my inquiry poorly. The reply was essentially "if VW could have tuned it for less soot they would have" and that no tunes are going to be beneficial in this regard. My thought was that something in VW's "fix" tune changed and is causing more frequent DPF failures, so why isn't it possible that that could be undone with a tune? Perhaps the "fix" tune that finally made the EPA happy is just particularly hard on DPFs. Was the member here who reported less frequent regens mistaken that the tune could have anything to do with his observations? Does anyone else have evidence that either the Kerma or Malone tunes are beneficial to the emissions system?
I know the easy solution is to simply delete. I'm not quite ready to go there yet, so I'm torn. So I spend the money for a Kerma tune and hope that I see the same benefits that another member here does re: DPF health? As Kerma does not offer a delete tune, I'd be stuck spending still more at some point in the future if I do delete. Then again, Malone says that their non-delete tune won't help the DPF any, and that Kerma's can't either, period. I'm not sure what to think at this point!
Any thoughts would be very much appreciated. I hope I've explained my dilemma adequately; please feel free to ask for clarification if necessary.
Thanks in advance!
