Tune on a mostly stock SS?

A tune will net you some hp, make your car more efficient, Might even increase your mpg... But its not necessary with just gears and a CAI.

Thanks. I'm mostly interested in getting better throttle response and wondering if a 93 tune will be noticeable. Not really interested in getting headers.

Your stock tune is a 93-octane tune.

Have you checked into a throttle response controller?

It is? I thought it was 91?

It's recommended to run the highest octane you can get. The stock system is designed to run with a little bit of occasional knock retard. With 91 it will just start this a little bit sooner and a little bit more. You won't pick up anything trying to tune for 93.

I put a pedal commander on my 2010SS and it made a big difference in the response when you hit the skinny pedal. It doesnt "tune" it or add any additional power, just speeds up the signal when you hit the pedal. It has a bunch of different levels so you can dial it in to what you like

Yep. Did the same with mine and still have it in the car. I rarely, if ever use it, since headers, high flows, Corsa catback, and tune.

Thanks for the input from everybody. I guess the consensus is it would be a waste of money unless I get headers.

i recommend the pedal commander, they are about $200 bucks and it really felt like it "woke up" the throttle response in my 2010 SS overall. It takes 5 mins or less to install or remove. Again, it doesnt add any power or torque. It just speeds up the signal, so there is no delay or lag when you hit the throttle from a dead stop, or at any RPM...

yes. 91 or better. And frankly no mail order tune or similar is going to be a strict 93. And even if it was, would make no measurable diff on a stock car. I know you said you're not terribly interested in headers, but if you want any gains you can feel, and not artificial peddle position stuff (e.g. Pedal Commander), then I'd suggest headers and a proper dyno tune. That is where you will see real world differences.

I think it really depends whether or not you have an auto or manual. The automatics all have some form of torque management, no? I'm not sure if this is also on the ZL1's or not, however... The ZL1's all use the same LSA engine setup, so they don't physically have differences, unlike the L99 and LS3 in the SS models.

I drive a manual LS3 and notice how sensitive and strong the "tip in" is, basically requiring me to feather the throttle pedal sometimes, especially when I'm trying to creep the car around or in traffic. I've even used the cheaper, generic pedal controllers, but before I was tuned. It only basically cut down the power a bit to be manageable to tip into the throttle for taking off, launching, etc.

Aside from that, if you look up actual tuning, there's really not a whole lot you can actually do, without frying the computer or being able to make an actual, significant change. There's terms and numerical values on some posts in this forum, I just can't recall at the top of my head. All I know, is that a lot of members have experienced a lot of the powerband with the later speed and rev range, feeling like it's "weaker", since a lot of the tip-in power is focused to that point.

I completely took mine out, which was a cheap, generic version, when I got an actual tune/tuner. Doesn't it mess with the tune? I can't imagine it would be any less simpler....

Honestly, it’s been so long since I tried it that, I don’t think I could give a good answer. So…next time out, I’ll give it a shot. I think it will just it will just open the throttle sooner/faster, depending on setting. Which is what they do, regardless if tuned or not.

Agree with the guys above. If you don't plan on getting any LT headers, a tune would be a waste of money, since your gear swap was done at the dealer and the speedo calibrated at the time, it would be a waste. Depending on which CAI you have, the ECU can compensate for the extra air flow and adjust the AFR to be good. You should have noticed a bit better throttle response with it as well, I did with mine, back when I installed it. I have the K&N Tyhpoon.
