Tuned 2011 Ltz 6.2

[FlameRed2010 NHT]

I did a tune on my 2011 Silverado EC 4x4.

 

I bought the LTZ with all the bells and whistles (Sunroof, Touch Screen, DVD, yadda yadda)

 

Before this, I had a 2010 Dodge Ram with the 5.7 Hemi. I thought that was a powerful truck.....

 

 

Well, when I went back to Chev, I remembered why I didn't buy a Chev when I bought the Ram. Because of the 5.3, the 3.08 rear end...Save me, please.

 

So I ordered one with the feaures I wanted, the 6.2, 3.73 rear end, and the right color interior. (black looks nice clean, shows every spec of dust)

 

I took it in and had a K&N CAI kit put on, and while I was there, I was talked into having a custom Dyno tune done.

 

Long story short. I am @ 404 RWHP, getting 23.2 MPG highway, and timed 0-60 readings of 5.7 seconds on cooler days.

 

I will say, if you think saving $3 a fill up is worth it by buying 87 octane...HA. You can feel the timing retardation. First vehicle I have had that I could notice. The Ram said to run 89. It didn't make much of a difference on 87.

 

Fast truck. Getting over 120 mph takes no effort.

 

I have been browsing here for a few weeks since getting my truck. I like the pics of your guy's trucks. Some of the appearance mods I am seeing make me jealous!!!

Congrats on the new truck. I have the same truck and absolutely love it. I'm getting a custom tune next weekend and can't wait.

 

Welcome to the site. Post up some photos when you get a chance.

I just hit 1000 miles on my SLT 6.2. I love it!! I got my tonneau cover and now I just need to get a Denali grille. This truck is as fast as the car I drive at work...

[Stevens03]

I have the denali grill and chrome tow hooks. I love it

Wait, with just a tune and a CAI your at 404 rear wheel horse power and getting 23 MPG on the highway? Am i missing something here, or did i misread?

Conograts on the new truck....WOW 404 rear wheel horse power ........FOR REAL????? What were your numbers before the tune? I would be dancin in the streets for that indeed,,,,

404 hp at the rw does seem high, since it makes 403 at the flywheel stock on e85, you'd have to put around 450-475 flywheel to have that at the rear wheels.

If it's 20% parasitic loss in the drivetrain, it would be over 500 at the crank.

 

That's one generous dyno for sure.

23 mpgs sounds realistic

6.2 engines are the best for sure. But yours is great!! Where did you get your tune? I had Justin do mine but it's not like that. He's in trouble now.

404 RWH and 23 MPG!! The best I ever seen without serious engine mods. Are you sure that is not flywheel hp ?

Slow down Louie, Justin is one of the best tuners out there and if he could get you those numbers he would, something is fishy with the original post.

[05GMCZ71]

We sometimes get people like this coming on, mostly to claim they have a new truck that is having all kinds of service issues. They are usually trolls from other forums (toyota, ford, dodge) who just like to cause a little contention.

[Stevens03]

I understand the numbers are inflated some, I have the same truck. But if he's happy, thats great. I don't think from the post, he sounded like a troll. If I drive under 60mp, I've seen 19mpg and I'm not tuned either. On all my trucks I've had tuned, I've seen a 1-2 mpg better mileage so it's close I suppose.

[Wingnut]

The MPG claim is perfectly reasonable. Several people here (including me) have been pretty close to that number (and I wasn't tuned either)...It's his dyno number that is highly suspect.
