You car is sure pulling hard! Heard from Tadge Juechter, Chief Engineer, that they tested it in Eco mode and got a maximum of 90 MPH. The were surprised when one of the media analysts said they got it to just under 100 in Eco mode. Wondering if you car is not "cylinder deactivating," but always staying in eight cylinder mode, or if you car is registering Eco mode, but really isn't (can't remember whether you have an auto or manual trans), but something isn't adding up.

Maybe they made a mistake and put a prototype 2015 Z06 motor in yours? LOL

Wish. Mine actually slow compared to some guys stingrays.

Cylinder deactivation is only between 1200 to 2900rpms & on light throttle. Goes back to v8 when those conditions are no longer met. Like going up a steep hill.

I read an article about throttle progression & not getting full power except in track mode in race ptm mode but i dont think its true.
I should make a drag strip run in eco mode lol. .

Thanks for finding out that information.

does going to the different modes changes the tune other than activating the eco 4-8 cylinder?? I would think no, but got carious.

GM said changes throttle progression in the modes.
But I never read that it limits power at all. The VBox performance meter measures G forces. Easiest thing. I just do two 3rd gear pulls in each mode see if any noticeable change in G force

interesting... this might explain why my throttle won't go 100% below 3000rpm on some of the runs I logged. Thanks for the info!
