Ktuner v2 dual tune.
 

I suspect that there may be a few more people in the Civic forum that have tuned their cars.

I have a 2018 CRV Touring and want to add some pep to the performance.

What is the experience among you folks with this product? Any real benefits and downsides?

welcome to the forum any type of chip or mod to the engine for your 2018 cr-v may/will void your warranty. as long as your car is under warranty, as the service manager if you can install a mod with their permission or have them install it. at palmdale honda when i purchased my 02 civic, i talked with the service mgr and he said i purchase the part, they install it and the warranty would not be void if anything happened. i did have a 100k extended warranty so for the first 100k miles all work was done at honda dealer. expensive but i had no worries of failure of any type.
