Decent fuel mileage for 6.2 this was with down town driving with several red light's, running as fast as 75 mph with cruise control on. Also best 1/8 time with slip.

Nice. Looks like it should be 13.6/7 for a 1/4 mile as long as the governor doesn't hurt you. Surprised i have not seen any performance threads on these new 6.2 trucks. I have been wondering what kind

Trivia: '83 6.2s with-the-Early-Heads got similar mileage.  No governor but I suspect lower gearing - I have never taken mine over maybe 70mph, though it will go faster.  Later 6.2s of that era d

Wasnt sure which tire set up you had. Some have tires rated lower and so the governor is only 98 mph. Mine goes to 114 too.

It all depends on the tire speed rating that truck was born with.

I assume this is a top gear limiter like in other vehicles?  In other words, 112 mph in 10th gear.  So you could downshift and go faster (at least that is how it worked in the 5th Gen Camaros).  Thus it also wouldn't affect 1/4 mile.

That is interesting. I have never heard off that. I kinda doubt it because anytime i have hit a limiter it has not been in top gear. Its restricted based on tire ratings so i don't think the gear has any role in the limiter. On a camaro that could he completely different since the tires are probably rated for more than the car will do.

      Silverado 4500-5500-6500 are they still being produced? Would have sold better as GMCs as well

      By C/K Man · Posted

      There was talk over the last couple of years that the contract to build these trucks between GM and International would not be renewed.  International moved production of all their other trucks besides the companion CV model out of the Springfield plant some time ago when they opened their San Antonio plant.  That left Springfield only building the Silverado Medium Duty, International CV Series, and some Express/Savanna long wheelbase cutaways.  International also put the plant up for sale some time ago.  This all answered my earlier question as to why GM and International did nothing with these trucks since they were introduced, as they had basically become a market 'placeholder' with a finite life.    The Silverado Medium Duty/International CV trucks were interesting combination of a GM powertrain, electrical system, and K2XX Silverado cab with an International chassis that was supposedly designed for a step-van type vehicle they never produced.  They were manufactured in International's Springfield plant along with the IH MV series initially.  When first introduced, there was much talk that the Silverado Medium Duty/CV would eventually get a gasoline engine option along with other upgrades and GM and IH would work on a class 6/7 joint venture truck.  This was before VW bought Navistar out, after that happened no more was said.  Draw your own conclusions...   About the time talk started that the GM/IH joint venture was not going to be renewed, rumors started that GM would develop a new line of medium duty trucks themselves.  The story is the new trucks will be part of the next generation HD's due in 2028, and will still feature a 'straight rail' chassis design that the current medium duty has.  GM views this as a desirable feature that differentiates their truck from the competition.  A gasoline engine option is also expected.  As the current Silverado Medium Duty remains in production until September 2026 and there is still a lot of inventory available do not expect any official word for some time.   I believe GM remains committed to their successful partnership with Isuzu, and all the LCF models will still be available from Chevy Commercial dealers.  Isuzu is on the cusp of opening a new large plant in South Carolina and there is also speculation that this may result in new product for both Isuzu and Chevy Commercial dealers.

      Software Update

      By nfisherman · Posted

      I have a 2026 2500 HD Ultimate. My phone app says there’s a software update available. It’s something about improved battery management and something to do with the running boards. I follow the instructions for the update but the “Check for Updates” option is greyed out in my settings menu. Has anyone else seen this? How did you resolve it? The help message just says “see your dealer” if the download doesn’t work. I’m just trying to save a trip.

      Exhaust Question

      By newdude · Posted

      Fuel mileage?  That's all how you use your right foot.  Exhaust will give you sound.   Stock exhaust 5.3 is 2.75" diameter piping.     If the truck is nice and worth putting some $$ into it, I'd go for a Corsa catback.  I had one on my 2019 old body 5.3 and it was just perfect.  Zero drone, just driving around and cruising on the highway you'd think it was stock, but when you opened it up it was like a Camaro with the factory dual mode.  Corsa bumps their catback to 3in diameter.
