Default 2018 C7 Backfire Issue
When my 2018 Corvette is in sport mode with open exhaust, under full throttle, it backfires when it shifts from 1st to 2nd The dealership said this is a common problem with the C7 and showed me a printout of the issue. Does anyone else have the issue or know if there is a fix?

Welcome to the forum and congratulations on your C7!
I would suggest you will probably have a better response posting this question directly in the C7 Tech section of the forum at https://www.corvetteforum.com/forums...rformance-169/.
Hopefully this is nothing significant.

Normal and awesome. My M7 will do it occasionally under the right conditions, but it always puts a bigger smile on my face!!! Passengers just yell "Holy Sh#@"

Not really an issue so there is no fix. There would be a lot of complaints if they did fix it.

It's perfectly normal since it cuts fuel and timing rapidly for the shift.

The dealership said it's a common problem and showed you a printout ??? Uhhh what........ ?? It's not a "problem" at all. It's completely normal and exactly what it's designed to do.

There's a Nurburgring video in the C8 Forum where the new C8 repeatedly hits that 'POP" as the guy is manuvering around the course. Sounds So GOOD!

The only problem is that the exhaust doesn't do it all the time!

I was actually wondering if I could get more pops and bangs added when I get my ride tuned. Is it just a case of dumping extra fuel into the cylinders when letting off the throttle?
