I'm considering proven as well, but having had and really liked GDE on my Ecodiesel I'm very interested in what they come up with. Getting greater than ~150 miles between regens and the turbo brake along with everything else would be very nice to have (again).Yea, I hear good things about them, their shop is about an hour from my house, so is AMPD actually.Dunno what to tell ya. Many happy happy Proven users. Good luck in your search.
The reason I am waiting to see if GDE comes out with a tune for our trucks is I am actually quite satisfied with the factory power levels and drivability, like I said in my earlier post, a turbo brake for towing paired with the factory grade shifting and lessened re-gens would really make a great package even better.
if I was after a delete or more power I wouldn't have any reason to wait, and I still may try Proven come bonus season in February.. just to try a delete tune to see how I like it.
Does anyone in a colder climate have experience with the warmup ∆t with the EGR bypassed/deleted ? would it even affect warmup times or does the EGR stay closed until its warmed up ?
Last week it was -15 degC as expected the truck started like a champ, warmup took ~20 min with moderate inner city stop and go traffic.
