Bottom end with the V8’s, not comparable to a V8, rather a V6. Great motor but max towing is 6700#’s, the 5.3 with towing package is 1200#’s. All in all, great little motor, give it a thumbs up for mpgs and being able to move the full size truck minus the 300-400 lb difference in weight difference compared to a 5.3 but not for towing which is what full size trucks are needed for. GM says that 90% full size trucks are used as grocery haulers but I’ve never hauled groceries, just heavy trailers.

Ok, congratulations and good luck, I’m outta here!

This thing has almost as much torque as the 5.3L though and at 2K less RPM?

Anybody end up getting that AFE intake?  I'm considering it and wanted to know the results?  Power is fine but i'm looking to hear more of that turbo Whistle

I love my 2.7T. However, I am in the camp that doesn't pull anything besides a golf cart. I don't understand some on this forum with all the hate - when it comes down to it, if we needed a truck that pulls 9,000 lbs we would buy the truck that pulls 9,000 lbs.

 

Honestly, IMO, I think one of the problems with the new engine is the lack of branding. I know I'll roasted for saying this, but Ford (knowing the public perception of a smaller, turbo charged engine) did a great job of branding it and making it consistent across the board. Not saying it's a fantastic lineup or anything, I have never even driven one, but 99% of people shopping for a car knows what an EcoBoost is. All that to say, I think if GM did a better job to brand these engines (so Skippy's on public forums don't just bash it without ever driving it) and market these engines early to overcome the perceptions, we would be in a different place. Instead, it took the route of "See for yourself."

V8 owners dogs the new 2.7 turbo. Before my current 2019 Silverado crew cab RST with the hated 4 cylinder, I owned a 2010 Silverado double cab 5.3 6 speed with intake, exhaust and edge tuner. Performance wise compared to my current truck the 5.3 does have a bit more off the line power, otherwise feels very the same as far as accelerating. Before deciding with the 2.7 I drove the new v8 5.3, v6 4.3, then lastly the 4 cylinder. Keep in mind that I was very skeptical as 99% of owners here. The 5.3 felt right, v6 was just straight crap and the 2.7 surprised me. For my purpose of using the truck which is a grocery getter, family hauler, trash hauler and just to have a vehicle to load anything big and the fact that I will probably never pull anything, it just didnt justify the extra $$$ to go with the v8. My first test was when I hauled atleast 1200# of trash to the dump site, besides putting a bit more pressure on the brakes, this small motor handled it really well to were I almost couldnt tell that the bed was loaded. Fuel mileage wise it does exceed my girlfriend's 2016 lexus nx200t which is probably half the weight with my averaging 20mpg to her 18mpg. My old 2010 silverado was lucky to see 15mpg especially with all the stop and go traffic and short distance freeways we have here in Hawaii.  From my personal usage, to the great price I got and the cool whistle of the turbo and surprising power I'm glad I got this one. 

This 2.7 in a full size truck works for some people. So why beat them up over it.

A V8 1500 will tow literally twice what that thing will.

Please tell us all again how it's got more power than a V8. Please.

I have a 2020 GMC Sierra SLE 2WD crew cab with the 2.7L.

 

It has the preferred and convenience packages. 

I was out the door at $34,700.

 

I added the aFe momentum gt intake, Borla s type performance exhaust, I am getting it tuned by a local GM aftermarket performance shop in GA and it first dynoed with scorcher and bolt ons at 310hp/340lb/ft to the wheels with 87 octane

 

So to the crank, I have about 350 hp and 390lb/ft. 

 

0-60 almost 6 secs.

 

I get 24.4mpg on the highway and 19mpg in the city.

 

I have a 2 inch leveling kit and have 275/65R20 wrangler Trailrunner AT (34 inch tires). 

 

It is my daily driver, and I never tow. 

 

It is faster than a 5.3l and about as fast as a 6.2 when both are stock 0-60mph time wise.

 

Torque peaks at 1500 rpm. It was built by GM to give turbo diesel like performance to a gas motor.

 

It's not for everyone. But to belittle it's performance is ignorant, but Skippy that sounds like your M.O.

 

But it does sound like civic

"It is faster than a 5.3l and about as fast as a 6.2 when both are stock 0-60mph time wise."

 

First your truck is tuned, so it being faster than a 5.3L that would be a nice race. They are tested by car and driver at 6.1 secs. 

 

Second, it won't be close to a 6.2L my man, they run 5.3 secs from 0-60 mph.  That's not a close race! 

 

Third, I am not bashing your truck at all, I think GM hit a home run on this engine. I have heard nothing but great things about these trucks. I am constantly reading articles, and TFL truck clips about vehicles, and Andre' from TFL said he couldn't tell it was a 4 cylinder when he drove it. I am intrigued by this and will be stopping by the dealership to drive one just for $h!ts and giggles. 

 

Take care and enjoy your truck

Just ran it today and got 5.6 on 0-60. So about as fast now as a stock 6.2l.

 

It's different strokes for different folks. 

 

Would love your thoughts after you test drive it. 

 

Cheers

WOW!!! Those are some pretty impressive numbers. All the magazines 0-60 times were at around 7 secs. So you're telling me that a tune, exhaust, and CAI, plus, you have your truck lifted with bigger tires and you knocked off 1.4secs!?!?  That's amazing man! 

 

GM  has a winner for sure on their hands if that is the case. Congrats on those upgrades because you FOR SURE got your money's worth with those upgrades. Just imagine if you upgraded the turbo on that thing. I remember my buddy had a 2013 Limited Furd 3.5L ecoboost, and he replaced the turbine wheels with bigger ones and the gains were unreal. Maybe you could do that with yours??

 

Would love to see you find a Trailboss with a 5.3L and one with a 6.2L and see how they stack up against yours, since yours has a lift was well. 

 

My dealership doesn't have any in stock. Kinda disappointed. They don't even have any 3.0L baby Duramax's in either. All they have here are 5.3Ls  and 6.2Ls.  Might have to stop at Billion Auto on my way to the lake house this weekend and take one of theirs for a drive.

 

Take care and again congrats.

It was running a 6.6 sec 0-60 stock. 6.5 secs on 93 octane.

 

I ran it on 93 octane. The leveling kit I have isn't terribly high, 2 inches. The tires went from 275/60R20 to 275/65R20

 

I added roughly 75 hp 95 lb/ft on the Dyno.

 

The tune and changing the shift points plus improving throttle response with a pedal commander really helped off the line.

It’s been pretty easy to get a turbo engine to perform with mods especially adding boosts. The real trick is longevity. Of course factory boosted engines often have built in margins of tolerance and can handle a little more than factory boost. Finding the line is the trick.

That's awesome man. With those numbers you can hang with the 2.7L ecobust from Furd. 

 

I didn't know you could tune a 2.7L??  Wonder why they allow them to be tuned and not the 5.3L and 6.2L without paying out of our @$$es for it?? Or did you have to send yours into HP Tuners?

[CamGTP]

I want to know this as well. I have heard and seen nothing about computer calibration/tuning for the 2.7 Turbo engines.

 

 

[TNTSierra]

I am still waiting on the info on how he tuned his 2.7L? Who did he go with? Please share with us

Who did your tune and how did they tune your shift points?  I was under the impression the software required to tune these PCM's wasnt readily available to the public unless you purchased a cracked PCM and utilized expensive proprietary software?  I'm very curious to know how you got yours tuned and were able to adjust the shift points on the transmission if you didn't go that route.  A budget based tune would make a lot of people very happy right now.
