Purchased the performance chip, set to 91 octane, spark plugs (required) and the oil catch can (recommended). Mine is a 2019 2.0 Turbo. Performance as represented, nice increase feels more powerful across the range. Would be a five rating except no housing for the chip included. Had to fabricate and mount myself. Also the YouTube video for installation was for an older model, close but not exact. Luckily my friend is a Mechanic and easily figured it out but not ideal considering the cost of the parts and the job being performed. Device was fun. Delivery a little slow but I am at the other side of the continent. Overall, nice performance parts but be prepared to do some work to install. BTW, I notice that only 5 star ratings are posted on the K5 Performance store internal ratings. I posted the same 4 star rating as here and never made it on. Therefore be careful about those ratings, David only posts ratings that are completely favourable to him.
