Cured from V8 Bug

This^ my LLT shifts just before redline at WOT while in sport mode. I always drive around in sport mode. However I'm going to use drive on my road trip to the cities to see what kind of MPG I get. I should be able to control myself being my GF will be with me, and she doesn't like to drive spiritedly like I do.

I got 24MPG while in sport mode driving to OK ~1,000 miles. But I was cruising pretty quickly.

SimpleGreen & AngryBird: maybe you're right! Guess since I've been focused on getting good mpg, I might be driving it a bit conservative. I've notived that the car's mpg ave suffers most from 0-40 mph, accelerating from stop to around 4th gear--it eats up gas in that range, but after that it's great with mpg.

Be right back boyz---I'll be taking my 1LT for a little spin and try the sport mode paddle shifting in the 3-4k rpm range and see what happens.

Perhaps this car just likes more agressive driving. That's cool, but I don't want 20mpg avg, EITHER---for that I'll rather have a v8, lol.

Don't even worry about the paddles. Just let her ride in 'M' and shift auto. Just don't act like the go pedal is an egg shell. I'm averaging 25MPG and I'm not by any means the slow car on the road.

Spartan--yep, this car shines on hwy. Has no problem accelerating past 4th around the 40-50mph+ range. It's fun to set it to cruise control 75mph on hwy, and whatch the mph avg keep rising--amazing. However, making the most mpg from 1-4th, 0-40 mph, city driving, it's a different story---gotta be easier on throttle, cause accelerating agressively from dead stop to 4th, up to around 40 mph, it eats up gas, LOL

The only other thing I can say is....ignore your MPG on your DIC. Your just gonna over analyze it constantly, lol. Reset it at the start of the tank, drive the car how you see fit, check it when your dry

Word! Drive the car, have fun. It it costs $3 more a tank to drive how does that compare to the payment? This is a 323 HP car not a Nissan Sentra!!

I wish the LS had a sport mode. I am hoping the engine/transmission tune I get with the RX Supercharger plus the gears I plan on installing make it much better.

Well, just came back from little experiment drive. Started my stealth fighter up, and looked through my CD case, popped in Alter Bridge, "Ties that Bind", turned vol up, and hit the road on Sport mode, no paddles.[ Reset mpg avg MPG and then blasted some Creed, "Bullets".]

Took a trip around city, 10 miles. Avg speed was 22 mph (stopping, slowing down, etc). Had about 5 stop signs, 5 traffic lights. This time I accelerated more agressively, aroround 2500-3000 rpm untill I got to 45-50mph, and then "coasted" keeping it around 1200 rpm, and man, this car loves it. Great combo. Had to pass a slow a$$ truck in front of me slowing everyone down, and crossed 2 over-passes (uphill).

Looked at my avg MPG DIC, and 24.1 mpg avg

Amazing for a city drive! From now on, will only drive in Sport mode

Don't think of an SS with spray...

No SS here, just the v6, but man an SS with even 75 shot of NOS would be crazy!

Love the challenge of the v6 and making the most of it. I think that installing a nos kit, leaning to one of those 3ple Threat kits, is a great way to have the 70-100 hp and torque ready to fire when needed, and thus have the SS feel and more at the flip of a hidden switch, for about $800, instead of paying $6000 for a supercharger.

[Yohan]

Just noticed an interesting fact:

The SS trim comes with 426hp/420ft-lbs torque = 1.01 hp/torque ratio.

However, my 2012 1LT has 323hp/278ft-lbs torque, which = 1.16 hp/torque ratio.

Perhaps its this torque difference in the v6 that makes it feel a bit heavy/sluggish when accelerating...my CAI defenitely help a bit in the low end feel, but still not as agressive as I'd like. Just needs a little more throttle response on low-end. Perhaps the Rx ported TB will help a bit more in this regard.

Do you have a tune yet? You should see the night and day difference a tune makes on the automatics. We can make it shift harder and faster, and hold gears longer. Plus you get more power out of the car.

No tune yet, but have heard of the trifecta tunes, its def something i'd try. An A6 with 323 hp should b feel more responsive and accelerate more effortlessly than what its set from factory. My wife's old 2004 sequoia tank with 240 hp snaps ur head back into seat when tapping throttle, yet my camaro v6 I have to aggresively step on gss around the 2500-3000 rpm range to feel like its alive? No way...its should feel like that at 1500 rpm, like an old freakin Sequoia, at least, lol.

GM def set some conservative parameters at low end. If a tune can make the car shift and accelerate better, increasing responsiveness, it would b sweet. Instead, to make it accelerate nicely i have to rev it around 3k rpm! It should b able to feel responsive @1500-2000rpm instead, no?

For the a6 v6, we get 323 hp, but only 278 ft lb torque to move the 3700 lb beast. However, SS get 426hp and 420 ft lb torque, very close, for almost a 1:1 ratio.

The v6 should have something like 315-320 ft lb torque to get that similar to SS hp/torque ratio. Maybe GM purposely programed a torque reduction, or maybe its just the gearing.
