i'm not going to arguee or lie to anybody to make or save a sale, anybody that knows me knows i will tell it how it is. like i said, you will get the best mileage increase w/ taking off the DPF but, your talking about saving the warranty. so your saying that he would be better off taking off the DPF, getting a custom dpf delete tune, then if he ever has a problem, put it back to stock and he won't have any problems at the dealer...?
i've heard from a few people that they've had problems w/ the filter on a 100% stock truck. also i've talked to more people than you have about their Edge units in their 08s, and
not everybody says they get another 3-4 mpg some people say they have only seen 1 and some none. BUT i have
never had anybody tell me they lost mileage. we've only had 3 returns on them and it was either b/c the unit didn't have the full program in it or the probe was bad or the monitor didn't read anything. believe me you will always hear more of the bad than good on the internet. and i'm not denying the fact that it will cause more regens but simply stating that he wil most likely get better mileage and, once the unit is taken out, will be undetectable by the dealer.
believe me we wouldn't sell so many if they were as crappy as you guys are making them out to be.
