Just picked up my 2024 Silverado 1500 with the Turbo Max Engine. The Window Sticker states: • 5 YEAR / 100, 000 MILE* POWERTRAIN LIMITED WARRANTY, ROADSIDE ASSISTANCE &
COURTESY TRANSPORTATION. Nice suprise for me.

Love my TurboMax. Averaging 15 MPG pulling a 5800 lb travel trailer for 2 years across the country. 0:15 11, 000 miles so far.

Another way to tell which country any vehicle was manufactured in is the very first digit of the VIN. 1 is USA, 2 is Canada, 3 is Mexico, and there are numbers for all the other countries also.

Thank you for the video. I drive between Vegas and AZ on speedway 93. MPG dumps to 13 to 14 above 90mpg. Appreciate the insight on use of the turbo. A little over a year in with a high output Sierra, really happy with the performance, although mpg can be finicky.

Nice Video! Just got 24 mpg on a road trip with my 2012 Chevy Suburban 5.3 liter V8 - 60 to 65 mpg.

I'm running a K&N air filter in my truck, seems to work really well.

Good info on the mph vs mpg. Often wondered what speed gives the best economy empty.

Mind (23) consumed oil for 15000 miles or so.. not sure what was going on because now it doesn’t consume any oil.. love the truck

[jimparker]

If you have the time, geek-out on the technical details of these 2.7 GM four cylinder engines. The overall power and economy are amazing compared to the Gen-4 eight-cylinder in my Silverado.

Vin # will also tell you where it’s manufactured. Starts with 1 (US), starts with 2 (CAN), starts with 3 (MEX).

I live in North Hamilton county. Enjoyed the video.

Torque comes on at 1500 rpm so it's spirited for me. Another like is the electric water pump that keeps going after a shut down. I try to stay out of the turbo and on a flat freeway, 1500 rpm in 8th gear is about 68 mph so it's relaxed cruising.

Another great vid with nice info nuggets.
I like your brain Jerem.

[JerodDowell]

Cool. What do you think about the factory GM controller that goes in the dash?

2023 Silverado 2.7 HO custom trail boss at 10, 400 trouble free miles.

My 88 GMC with the 5.7L is the same way, It'll go 70*75 down the highway but You will notice a substantial difference in milage. I keep it at 65 and it's not bad. At 75 it's guzzling gas, I suspect it's the rear gear ratio.

Cylinder Deactivation on a 4 banger, Only chevy could come up with that

[Ward]

My shop has a fleet of these Silverados with the HO L3B and every one I’ve driven just feels sluggish. Like the throttle response is just dead. The power comes on a little weird too as I feel like softly easing into 70% throttle accelerates the truck faster than if you just punch it. Like flooring it literally feels slower than gradually pushing into the throttle but not flooring it. It’s bizarre, almost like it pulls timing under WOT. It’s hard to tell sometimes if it’s the throttle, the transmission, or a combo of both but it just feels so laggy that it ends up constantly downshifting when it shouldn’t have to. I’ll be merging onto the highway so I’ll smoothly start rolling into the throttle and it just doesn’t seem to respond quick enough before it triggers an unnecessary downshift. The peak torque is 1500 yet it will downshift like it’s an atmospheric 2000cc four banger that makes peak torque at 8000rpm. It’s rough. Maybe they tune the fleet trucks differently? They’re definitely the HO versions though according to the window sticker.

Not trying to be "that" guy, but isn't the torque on the H.O. motor 430 lb-ft?
