The car is very new, so I doubt there is anything available as of yet. But if you want to be creative, you can see if the air filter number is the same as any other models, and start with AEM fitler. You could always make your own CAI and modify it for your vehicle.

You might be able to order some exterior CT5 Blackwing carbon fiber aero and see if you can make it fit.

 

been waiting on an intake and tune for my ct5v but nothing yet, hell id pay GM to put it back to 400hp as it was in the ct6 but they havent done tunes in years

 

Anything available from HP TUNERS ?

 

Yes jb4 just launched one. Go to Burger Motorsports website and search by brands. I’ve had it for about 2 weeks now. Brought my 0-60 from 4.9 to 4.2

 

What kind of hp and torque numbers ?

 

Email the people at Trifecta Tuning, they say they are coming out with a tune and are looking for people who have a CT5-V. News

I have used them for my 2016 Corvette and Impala and happy with the results.

 

I just got a 2021 CT5 and have been trying to find a tune up for it... A local race shop here in Florida told me you can't modify or change the ECU's? That there is nothing he can do? Find that strange. True?

 

This is 100% true. HP tuners have not found a way to crack the new ECU’s. GM is using a new type of system that makes it almost impossible to tune these cars. Your best bet is a piggy back system from Burger motorsports.

 

Thanks Jonathan, my dealer is looking into it too. Are you talking about the JB4? It's on the Burger site as a tuner for the CT5...

 

Yea that is what I’m talking about the JB4
