I appreciate your time and the answer. I guess I just need to slow down a little bit. Thanks again.

Didn’t think about that? Do you think if I run premium, it would be better

On the way up, mid 70s on the highway. The last hundred miles or so of the trip is all 2 Lane Rd. Speed limit from 60 all the way down to 25. Sunday on the way home between the snow and the traffic it was obviously less

Yes, for probably an hour or two during the trip? I was also switching back-and-forth between normal. And what I believe is the sport mode? Just trying to see what kind of difference there would be in the transmission.

I was thinking that too? I was just hoping because it’s a V nose it would’ve been a little easier on the truck? I got the trailer earlier this year

Is my towing mpg normal? I just got this truck 2 months ago. First time towing with it. 2022 refresh RST. 5.3 10sp 3.23 gear with 14,000 miles on it. Trailer is a Mission Crossover 101’’x12’ weight is 1100lbs. 2 sleds weight is approximately 975. 2 people in the truck. Went from Rockford IL to Ontonagon MI. 353 miles there, 60.3 average speed, 8.7mpg On the way home average speed was 56 and got 8 mpg. I was really surprised by how much the transmission kept shifting. I used the manual shift mode so it would either be in 8 or 9 Is this normal mpg? current mods: K&N cold air intake Borla Attack muffler

Thank you for response

I just purchased a used 2022 RST. It has 5.3 10spd trans 3.23 gear with 13,000 miles on it. According to the window sticker, the truck originally came with 18 inch wheels. Someone put the 20” black rims with Toyo Open Country A/T3 P295/55R20 tires on it. My question is this, how much will these tires have an effect on mpg and performance both normal driving and towing? (My truck does not have DFM from the factory)

One of the trucks I’m looking is a 2022 and it is not equipped with dynamic fuel management, or steering column lock. Are any of these a huge issue or problem?

Thank you all for your responses! I greatly appreciate it! Going to look at two trucks tonight

I am thinking about replacing my 2014 Silverado 5.3 6sp trans 3.42 with a 23-24 5.3 10sp 3.23. Has anyone else done this recently? If so, what are your impressions, thoughts? Good or bad. Thanks for the help.

thanks for the info. which tune did you have him do? 87 or 91? do you tow anything? if so noticeable difference?

thank you for the info. i'll start email him.

i have a 2014 silverado 5.3 6 speed 3:42. i've been running a diablo canned tune in my truck for a year now. i just did the 87 tune, afm delete, stock shift, max throttle. would there be a noticeable difference getting a Lew tune? i like the trucks drive ability just wondering if i can make it better. also if i went with the Lew tune would the trans stop "learning"? thanks for your help.

2014 i've owned since 2015. finally getting it the way i want
