There you go. The performance loss 4500 ASL on a naturally aspirated car is about right. Realize EVERY car in your area will have the same issue, although turbo cars can mitigate this to an extent.

Almost all benchmarks are carried out as close to sea level as possible. Temperature also makes a large difference.

If you test your car in the middle of a heatwave at 4500 ft, the density altitude becomes even worse, up to 5500-6000 ft, with correspondingly worse performance.

Looks like your starting from idle. Give it some gas before you release the brake. Take it up to 2k or more if you can

Everybody please read post number 15 before you continue to guess. The answer has been posted, it's absolutely , obviously , altitude.

Yep might help knock it down some. Have to play with it. Some cars respond better than others.

You need boost.

That will solve your high altitude blues.

Toggled it all the way down to ZERO and now it is by 5s... now I have a 0-60. Will do this test in a few. (Not that 2mph is much) https://youtu.be/dmshOpxI--U

Wow, the exhaust note from that V6 sounds awesome.

I agree. Newest 0-60 has a great sound!

Is that the standard exhaust or the NPP. It sounds like the standard to me but, it's hard to tell from inside the car on a cell phone video.

Really look forward to getting through break-in. I'm at 900 mi now.

Glen is 100% correct. I am in Denver at 5,280 above sea level and haven't been below 5 seconds on 0-60 yet in my 6M SS. As well, tire grip issues in the 40-50 degree high temps are also an issue. I also took the car up for high-wind and high-altitude(11,500ft) driving several days ago. Even in 40-60mph winds at 10-11k feet the car was very strong and felt great. Will post video of said driving ASAP.
