  1. Since when you do need to pass someone doing 30 over the limit? I can two lane pass someone doing 10 over pretty easy lol. Maybe it just really gets to people that they can't get to their destination 3 minutes faster. I drive for my job, so I see this happen all the time. I end up meeting them at the next stop light when they pass me and I honk my horn the second the light turns green because they are now slowing me down.....

  3. You don't drive like most people LOL..jk. My 2019 LD 5.3 I turned in averaged 14.5mpg for 48,412.7mi. That included lots of WOT and E85 in the spring/summer/fall (was dyno tuned for 93 and E85 as well). Best rolling 400mi average was 18.0 and that was set on 93 octane which I'd run in the winter. Even in my 2012 5.3 I'd get 14mpg winter/17mpg summer per tank. So far in my 22 2.7 HO the worst tank I've seen was 17.9mpg. Best was 22mpg. 9900mi my average is 19mpg. I ran a 100mi mpg loop, no faster than 60mph, pulled 26.5mpg on that loop. I drive the same style as before, aside from the copious amounts of WOT in the last truck. I've seen WOT with my 2.7 but not like before.

  4. Good points. The L3B non HO was designed to be a Ecoboost style product, in other words it uses copius amounts of boost for a given throttle input to optimize fuel burn to the limit of being able to run 87 avg pump octane fuels. It also OVERCOOLS the head and turbo and overheats the lower end to optimize IC engine design for economy and emissions. If driven at relatively low RPM it will boost to get that idealized balance. If full throttled it will needlessly overfuel. Folks here that are older school feather foots and short shifters will see idealized economy. This from a little over a year of driving it in high altitude ops with lots of weather and wind with one long run to Michigan at high speeds last summer for funeral.

  5. Well they're averages so it's easy to get dragged down by guys who tow a lot or do a lot of city driving or run lifts or offroad tires etc. I beat both those averages in my truck but I know for sure I'm an outlier. I also beat the highway EPA for my truck, I have in all my cars. But if I'm doing all city it can take a pretty bad nose dive, and that's where the 2.7 probably shines best if you can keep the boost down.

  7. Checked for vacuum leaks today, sprayed some ether by all the gaskets. Looks to be a tiny leak by the egr valve and next to the throttle body, I spent a hour getting all sorts of fuel trim readings so here’s the list maf unplugged at idle fuel trims good mag plugged back in, truck still running, fuel trims good maf reads 4.24g/second at idle as long as the truck stays running since the maf was plugged back in the fuel trims stay good when driving truck shut off and restarted with maf plugged in, fuel trims good, maf reading 9.05 at idle drove around the block, maf plugged in, fuel trims very high, maf reading 4.62 at idle I will get some gaskets on order and do new plenum, egr, and throttle body gaskets, plenum gaskets have been removed and reinstalled a fair few times so it could be leaking in the middle by the injectors aswell

  10. Your fuel dilution went down on the two most recent samples you pulled which is nice. What's with the bump in sulfation and oxidation?

  11. Glad you posted the exact specs, I had the exact size and brand that came with the truck when bought new but my speed limiter was at 98mph. I've read multiple threads and it seems 98 are set for this wheel/tire specification. So...maybe your truck was "mis-programmed" and maybe you got a recent OTA update and it got flashed to match the true spec of the truck.

  12. Death wish doing 100 on any road, things happen faster than you can react, you have to be driving 1/4 mile in front of where you are, easy on a race track, not so easy with the nitwits on the road these days. To answer your question other than changing the tires or gear ratio there shouldn't be anything that would affect the limiter. I wonder if the Onstar may have done it? you said same size tires but not the same tires? there can be big differences in the circumference of different brands of tires

  14. Most of my vehicles I hit the advertised average on the interstate at 70 mph over the years. Usually a tic better going west on the return trip. The most sensitive is the CRV. I rarely hit the the stickers HWY mileage. It’s is the smallest engine. I’m usually around 27 Hwy Mpgs. My wife’s Geneses a full sized car with 100 more HP does that. The Camry did 27 MPGs too. My 14 GMC was 22-24 Mpg with the 345 gear. The higher mileage was going 60 on HWY 17 going around an accident on interstate 95. I was such a nice drive I just stayed on it. I did get 30 Mpg with the CRV. I had a tail wind. The CRV does its best in town I have hit the same as the HWY mileage. I never hardly mash the throttle on the CRV. There’s no point.

  15. Mine never changed but the first time that I did hit the speed limiter it was during passing a vehicle and I was scared "ball-less " hitting that speed.

  16. The thing that puzzles me is that Fuelly.com is a very large sample. Chevrolet Silverado 1500 MPG - Actual MPG from 2,086 Chevrolet Silverado 1500 owners (fuelly.com) Take the offered link in example and limit the view to just the 2014 and newer Gen 5 motor. I count: 1073 trucks. 94,428 fills. 27,870,165 miles Almost 28 MILLION miles! And the result? Mid 16 mpg range across all years. This isn't 'drag down' by a few guys towing with lifts. This is what it is, and it looks like the 2.7 is following the pattern about 1.5 mpg higher. I can and have run 70 mph into a 20-mph headwind running E-85 and can't force it down to 16 mpg. The shop has let it idle in the parking lot of hours and hasn't run a tank down to 16 mpg. Fact is, it's never had a tank below 20 mpg. Not even in Rockford, Ill city traffic, the home of the 3-minute untimed stop lights. LOL. Fuelly shows it at 18mpg. I know @customboss gets better than the EPA average and it seems you do too, but really, what are people doing to these poor trucks to have so large a number do so poorly?

  17. Rotated every oil change Was thinking of doing that as the cheapest first option Thanks Tyler, I've had mud tires on my last 2 trucks (cooper stt pro) and these duratracs are by far the worst tire I've had. Just find it strange it's only on the inside and every other tread block. Just can't wrap my head around how that can happen. Seems we're in the exact same boat. Went with ko2 this go around It's not the loudness that bothered me I expect that with all aggressive tires. It was the vibration that really ****ed me up ahha

  18. Maybe 1 to 2 mpg better, but to me not worth the extra cost per gallon of gas. But it seemed like the truck ran good with higher octane.

  19. From the looks of what's on yours now, its the OEM "work" step. Affordable, simple boards, nothing fancy, rather plain. I'm not a fan of any boards (IMO) but my favorite has to be the pricey OEM High Clearance boards you can get on the AT4/Trail Boss trucks. Those are my favorite. And they finish them in a textured bed liner-esque finish.

  20. Yes and it sat for 4 days without being run. I purposely pulled it cold for that reason. At least 300 ppm is a fuel additive I am testing from RLI. The Amsoil did exceptionally well. NO AL wear is amazing for this design. The RLI 5w20 HD LA is 1% ash content. It will also clean for the time it was in use. Maybe 600 miles or so? I forget.
