For those on the fence about tuning

DO IT!!! DO IT NOW!!!

It's a substantial increase in both power and mileage. The first tank I was taking full advantage of the increased power available. My rear tires got a bit smaller. The computer said the mileage was 17.8 and the real mileage was 17. That's about what both those figures usually are when driving really, really conservatively. So far the computer is saying 22 and it's always been off by the same 5%, so the real mileage is about 21. It's right because I'm getting a lot more miles out of this tank than any before it.

This is awesome!!! And oh ya, NO MORE REGENS!!!!

Sorry. I dunno why my sig doesn't show up. I have a Mini Maxx, 4 inch exhaust, stock air filter (DEFINITELY staying with the stock air filter), and egr block off plates on it. Oh yeah, DELETED BABY!!!

This was the first tank where I was not driving like a total punk. I drove it this tank the way I usually drive, for good mileage. After a trip to work and back, the mileage was reading 21.5. Hand calculated was 20.5 and that's the same percentage difference it always is between the computer and reality. I know for sure I got a full tank on the refill because I filled it up all the way at one pump and drove to another pump and squeezed another 1/4 gallon in it. It has never gotten this high mileage before. I work every day until tuesday, and I usually get 16-17 hand calc. We'll see how it does now.

i doing 17.8 tank avg in Houston (mostly highway) but thats the whole tank. Bone Stock.

Idk, hard to go back to a tuned truck and worry about the warranty.... but they sure are cool...

if its an extra 3mpg, per tank, thats about 70-75 miles more per tank, at $3.89/gal (here) would be about $8/tank savings? 100 tanks and your even.

Good point. My calculations for my truck came up to about a savings of $6.50 a tank.

Worth every penny to me. Haha

Because it flows plenty of air and the filtration is REALLY good. I drove for four hours through a dust storm in the desert, and there was NOTHING, no sign that any of the dust got through the oem filter. Even on hot, full throttle to 80 mph, it didn't move the filter minder at all. It works too. I tested it.

I don't think everyone is going to keep seeing good mileage as the dpf gets older and more clogged up with non-burnables. And, the savings isn't really worth it based on fuel alone. The DPF will have to be replaced some time around 150 miles and that's going to cost at least 2500. The emissions sensors, DEF, engine wear, oil dilution, oil contamination with soot from the EGR, higher EGT at any given power output because of the EGR, and the additional fuel used all add up to waaaaaaaaay more than the fuel savings alone. All that plus I get a truck that smells like a diesel (I like that) and smokes like a diesel (I like that) and regen just annoyed me way too many times. Did I mention that it's WAY more fun to drive too?

I know it great for more power and better mileage but isn't it against the law to do the delete to your exaust system on these new truck?
