What screming just described above with regards to the car wanting to upshift, and fix by vince is exactly what im trying to say and accomplish...guess a tune is easiest way.

how much do those ported throttle bodies go for? honestly i think the money is well spent on a tune instead. its snaps your head back more. resets your computers knowledge of any driving habits
And as far as the whole "why get a tune" idea.. every car off the lot is restrictive due to emissions and state laws, so GM and other car companies have regulators or govenators to limit the cars performance.. tune it and let the beast outa the cage

and about the shifting.. mine never shifts under 3000. push it to redline! LFX can roar!

$165 with shipping after you send our old one back. There's a $200 core charge in the meantime.

Agreed that the A6 can come alive when flooring it or drving it agressively. Any v6 would do that as well if you drive it hard. Yes, my A6 1LT from a dead stop can launch and throw head back if I punch throttle and go wot, and at wot will redline shift...however, this is not what im worried or concerned about. Im not drag racing when going to work or daily driving, lol. So no need for wot, or rev it high to shift around 4000 rpm...this will eat up gas, and one of the big reasons I got the v6 was for mpg, too. Great car, good power, and great LFX engine that can give me 323 hp while also 24-26 avg mpg! If I wanted to drive it like a madman, amd not mind 18 avg mpg, I would have def gone SS route. Im sure with the auto SS, we dont have to punch the throttle to 3000-4000rpm pulling out of house to work to make it feel "alive".

Im just trying to figure out way to keep my nice 24 avg mpg, while getting my A6 V6 to feel responsive around 2000-2500 rpm. It's gotta be the Torque.

Hopefully a tb will help, amd surely a tune would do the same. Just wish I didnt have to spend money on that to begin with for a feel the car should have from factory, imo.

I second BNRs statement. The tune is well worth the cost.....shifts like a beast IMO!

The old sequoia in my example feels alive on a launch with a tap of throttle at around 1500rpm, where as in my A6, I have be agressive on throttle punching it around 3500rpm to get similar feel. Keep in mind im talking about normal driving, and not punching it at atrack.

In theory, the car should feel more responsive from factory. Its got the power. However, it seems gm went very conservative on low end responsiveness programming/set up, or the shift points are off, or the gearing.

Your really comparing apples to cookies though.

It's hard to find spec's on the 4.7L but I know it makes atleast 315tq at 3400 RPM. Your Camaro only makes 278tq at 4800 RPM. That is exactly why it feels good at 4000RPM and up. If you aren't driving the engine where it makes power, then it just doesn't make power. There is no magic trick to making a V6 drive like a V8 short of serious power adders. Big motors make power down low, little motors make power up high. That's why those Hondas have tachometers that get awful close to double digits.

My 1993 Chevrolet C1500 has a 5.3L LS V8 swapped into it. The engine is 100% stock, even still has the cast steel exhaust manifolds. It has a 4 speed automatic transmission. The only work is a custom computer tune. Stock the engine makes 285HP/335TQ. She feels VERY torquey off the line at low RPM and when running through the gears it feels like an animal. It would probably suck the paint off a 2004 Sequoia.

And down to the numbers, she's no faster than my Camaro

The car does have the power, you just aren't letting the car use it. A tune WILL make a noticeable difference, but it's not going to move the whole power band 2000RPM lower. The engine simply does not make power at 2000 RPM. Honestly, it's amazing with the cars high curb weight that what power it does have manages to move it around as well as it does. You'll gain back what GM took out with torque management and the extended shift points will keep the car in its happy place longer atleast.

Of course, this eats up my gas, man. Left at 24.6 mpg avg, and now I'm down to 24.1 after more agressive WOT driving to Home-Depot, LOL.
Mine shifts very close to redline into 2nd. I could video it. I also have the A6.

Actually the V6 does have a nice broad torque curve. Look at any dyno and you can see it is making good torque from aroune 2,500 all the way until about it starts dropping off around 5,400 or so rpm.

But its not enough TQ to snap your head back....lets say for example at 2,500 in 2nd gear. I find you need to be going around 40+ or mph to get the feeling in 2nd. Also I find if your wanting to play a bit or have fun with your passenger, while in manual mode let off the gas a tad so the rpms drop and then stab at the gas. Makes for a nice jerk that will surely make your passengers head bounce back. I once made my wife a bit annoyed because I got on it doing that once and her head slammed against the headrest lol.

Now in first gear...I find that I can hit it from any rpm...even very low and she will rip hard....but thats to be expected in first gear.

You guys can always get smaller rear gears to torque it up

Yohan love AB have all three albums! Seriously, you got to rev that thing, thats all it is. Get a catch can so youre not puking oil into the intake and let 'er rip!! I can hit about 100 in 3rd gear, this little car is under-rated! If there is a next Camaro, get the manual!!
What Simplegreen said too.

Wouldn't you want bigger gears for more torque? I believe the A6 is 2.97?

Great post, and yes those are the torque numbers for the '04 Sequoia 4.7L. With those torque numbers, even though its a brontosaurus at 4600lbs, it just jumps when u tap the throttle from dead stop, and gets up to speed quickly, effortless.

With our 1LT A6, at only 278ft lb tq, seems like it's kind of low for the weight of the car.

As noted on the SS---426hp/420 ftlb TQ, almost a 1:1 hp/tq ratio---it can effortlessly accelerate and doesnt need to be revved to 4000 rpm to feel alive getting normal driving or a little agressive, I'm sure.

However, for our V6, we only get 278, and wish it was more like 317-320 ft lb TQ, for a similar HP/TQ ratio of 1:1, like an SS.

So why only 278? Is because it was programmed from GM this way, shift points, etc., or the gearing is not as good?

In meantime, I've def learned so far that it's ok to be more agressive on throttle on this car---seems like it likes to revved as you said, and gets bored and sluggish w/ lower rpm, LOL.

Henry, ABIII & Creed, man

For now, I'll defenitely drive it in Sport mode, and use more rpm. For city, I just get up to 45-50mph faster, accelerating at 3-4ooo rpm, and once it hits 4th I just let it coast and keep it around 1200rpm and watch those mpg avg numbers soar, as I blast "Broken Wings", lol

Get the exhaust and CAI if you can afford it. It will enhance a tune and/or intake if you decide later to pull those triggers. Honestly there is a nice gain from both.

Got the CAI kit a few weeks ago, and lovin it. Now its a matter of making it more responsive in low end, and I think the ported TB should help.

Wish there were LFX programmers available already so I could play around with shift points. Someone mentioned that IFS Live reads the 2012? Wonder if hypertech is releasing something for our LFX anytime soon.

All V6s except the 2LS have 3.27 gearing.

Actually 278 TQ is not too bad for this engine. Sure, 300 TQ would be nice, but look at many other potent V6s out there and you will find their TQ numbers are quite a bit lower than their HP figure. My numbers aren't exact, but the mustang V6 makes around 273TQ, and even the all mighty 370Z makes no more TQ than our car does. But both of these cars offer lower gearing and weigh less and so their straightline performance is better.

Look at the new Cadillac ATS with the LFX V6. It has the exact same 3.27 gearing, but weighs only about 3460 lbs compared to the Camaro V6 3750 lbs. The ATS is rated at 5.4 seconds 0 - 60 while the Camaro was rated 4 or 5 tenths of a second slower to 60 than that. Put lower gearing or add bolt ons to that ATS and suddenly you could have a V6 that will do the 0 - 60 in under 5 seconds.

Did someone suggest a tune? Jeesshhh, this guy's peelin while upshifting have read and heard great things from Trifecta tunes. Will wait a little to see if there's a programmer out there for LFX to mess around with simple tunes myself. Not looking for fancy stuff--just need to upgrade those shiftpoints, and be able to "hide" the tune when going to dealer for SVC.
