It is very obvious that my 2013 9C1 is quicker by a long shot than my '95 LT1 Caprice. With 100 more hp and
50 more ftlbs this car goes. But the '95 is the tow package and has 2.92 gears with posi just like the '13 and it will smoke the tires without having to hold the brake pedal. I realize that is wasted motion but is sure is fun and looks cool.
My owners manual says to shut the traction control off press the button quickly for performance mode. The car will scratch a little but it goes and goes fast without any drama. I'm not complaining about the speed I just want to know if there is any other options within the cars system for shutting the Stabilitrac down?

you have to hold the traction control button down for about 10 seconds then you should get a notification on the information center saying stabiltrac disabled. I just recently discovered this option.

yeah but then once the car makes a little more power you run in to other issues... like it shifting thru first and second and then bogs in third and you just look lame... Its like this terrible middle stage between having a stock and a car that makes good power lol....

Very jealous of the 9c3 shifter

This is in the manual, 9-29.

"The TCS/StabiliTrak button is located on the console in front of the shift lever. The button can be used to enter StabiliTrak/TCS Off, On, and Performance modes. To enter the Off mode, press and hold the TCS/StabiliTrak button for five seconds. To return to the On mode, momentarily press and release the TCS/StabiliTrak button."

depending on the year model, even with the ST and TC turned completely off, there is still a significant amount of torque management (throttle delay or the gradual tip in of the throttle) that will occur with the factory programming. I did this on the my 2014 and it made a big difference but still not quite up to the task of legendary LT1 burnouts.

Of course Im sure there are several other factors affecting this such as:

LT1 possible making more torque than the L77 at lower RPMs. I think the LT1 peaked at 2400 compared to the L77 at 4400 but then again I dont know how much torque the L77 is making at 2400 RPM.

Platform difference. The newer Caprice is far better is in structure and is much more ridged and less prone to flexing. Also, mabe the independent rear plants the tires better than the 4 link live axle but this is just a guess.

The newer Caprice has a bit more rubber on the ground also and seems to have a much stronger limited slip unit than the B body.

And of course then there is the mechanical throttle linkage on the LT1 cars that in my opinion is far better than any drive by wire system I have seen.

Just a few ideas. I too have wondered how a car with almost 400 ft bls of torque with a super steep first gear doesn't just rip the tires all the time. You would think 1st gear would be useless but it tracks pretty well.

I forgot to add that my impression almost always has been the that all of the LS engines (Gen 3 and 4) seem to have less low end grunt than a similar sized Gen 1 or 2 engine.

I posted a photo a while back showing a cloud of smoke I made with my 2014 (with stock programming) and the only way I could do that was to turn off the TC/ST AND nail it with the wheel turned sharply at about 150-15mph causing the transmission to downshift to 1st gear putting the engine right in the meat of the power band (close to 4400) almost instantly while causing the car to fishtail and lose forward velocity.

what 91c said.

I have two 8.1L suburbans, both have 4:10 gears and 245-75-16, 455lbtq and they will no spin either. On the tucks and suv's they have throttle delay, drive train protection, torque management, something abuse, and a few other things......


I do understand what your saying. we had a beater 1500 silverado, 1994 model with the non vortec 350. 190hp 300? lb torque, falls on its face at 3000 rpms. but it would smoke both tires ( if you use the brake) all day long, or from a stop just floor it and one of the tires would light up like john force. fast forward to all the computer watch dogs and you cant burn out with 450 lbtq :roll: we dynoed my 02 last week when getting a ctsv tuned. 200K miles it did 239whp and 320lbtq from 2000-5000 rpms on tq. still cant do a brake stand or light a tire when pulling out...

As 9C1fanatic stated, there is a significant amount of Torque Management placed on our cars. One such layer of managment is the "Braked Torque Limit" table which limits the amount of torque the engine is allowed to make for a given Throttle Position and Manifold Pressure (engine load). So when the car sees the brake pedal depressed like when starting or doing a burnout, this table is envoked.

Shown below is the Braked Torque Limit table on my 2014 PPV's stock tune. Note that straight from GM, the car will not make more than 169 Ft-lbs of torque regardless of load or throttle position.

I just changed all the numbers to the max number permitted by the ECU.

There is so much left on the table with the factory tune on these cars, at least on my 2014. Just a straight tune to turn off the Torque Management and tweaking the PE (throttle responsiveness, etc) alone without changing the fuel or spark maps completely wakes up this car!
