What are your LC numbers if you don't mind me asking, I had crappy times with LC. Maybe my LC rpm is wrong.

I didn't mess with it, but I'll check to see what it is the next time I drive. I think it's 1700. Also, I run track ptm dry or sport 1.

Don't use PTM for good 0-60 times. Just use one of the regular modes. Ive got 3.4/3.5s in tour/sport and track. One 3.3 in sport comp at a prepped track. PTM is more for road coarse stuff.

practice for your best 60ft times and or 0-60 times without any nannies on, turn them all off. If you can get a 1.90 60ft time on OE tires you will get your pass 1/4 mile pass. Practice on a warm street (sunny day) after driving around for at least 10 miles to heat soak the tires, bring a tire pressure guage with you, lower rear tire pressure to 25psi and launch as hard as you can with out tire spin by the seat of your pants and no nannies. Leave the 10 speed auto in drive. I have gotten a 2.0 60ft time with a manual trans 6 cylinder 2016 camaro on the factory all season mud and snow rated 18 inch tires.

With the A10 1.7s are the norm at a drag strip on stock tires. I've got 1.67s on most of my passes. Don't use launch control it is contestant but wont net the best times.

This is surprising news for me about launching in the A10, I would expect Chevy programmed a great launch feature in this car with A10 making it easy to just mash it and go as long as tires are warmed up right. I had launch control in my SMG E46 M3 17 years ago, and it wasn’t great. By now auto engineers should have figured this out. I know it’s different with AWD, but launch control in a 991 911 Turbo gives you best acceleration with TC off and then you just floor it, over and over as much as you want. Computer sorts out traction to put power down better than human. Should be same with A10 ZL1.

1.7 60 ft times are not easy to get. You have to be real good feeling grip with your ass meter and know how to finesse the throttle. 1.9 60 ft times are easier to accomplish by the average driver. You also need to understand track heat, tire heat, track prep and tire pressure. Also need to know how to do a correct tire clean, burnout.

Nannies are for consistant launches, not for a quickest launch which gives you the best ET. A good driver can beat the best launch control controlled 60ft time for the most part once he/she is used there own car.

That may be true, but the margin of difference seems negligible in a 911 TTS. What people are reporting here with the state of the art A10 is surprising, Chevy engineers could have done better.

Also remember we are talking about about affordable main stream domestic vehicles (ford, dodge, chevrolet), not hi priced exotic german cars.

It works consistently on my car. I've never seen a 0 to 60 over 3.6 on warm dry days. Try doing that with a manual.

That's good to hear. Do you have to set rear tires to 25 lbs, do warmup burnouts, etc. or just punch it when you feel like it?

IMO, when we're talking about a car at the level of the ZL1 with a transmission like the A10, e-diff, advanced TC and PTM software, LT4, Magnaride/DSSV, etc I dont think this should be a caveat for power delivery and acceleration.

Yes it costs a lot less than exotics, but the technology, quality and value is there in the powertrain to do what those others do as far as putting the power down--and the power is there.

ZL1 and C8 Corvette have proven what we always knew, exotic cars are overpriced. I want one, but they're overpriced.
