Everything works beautifully and I'm not using a battery maintainer anymore because I'm driving the car at least 2-3 times a week. I also have a new AGM battery which I installed over the winter; however, the voltage reading with the new battery is the same as the 5 year old I replaced--replaced only because of age. Do I have a problem?

Still loving the C8 jagtoes? I'm still on the wait list for a C8 Z06.

Just turned 12K miles today and still having fun. Gonna put the winter tires on around thanksgiving. Enjoy the ride as life gets shorter. Good luck on the Z06 as they will be rare and it appears there are a lot of folks waiting. The official announcement is scheduled for Oct. 26 then the order books will open. Speculation is there will only be maybe 10K units a year.

My 11 XKR will vary from 180 to 212 depending on load and outside temps,,never had a car before that varied this much
especially on a supercharged car.
