So I recently purchased a 17 Focus ST 100% stock at 32,000 miles about 6 months ago. Since I got the car the vehicle is now stage 2+ and have gone stratified tuned. Something I’ve realized since I’ve owned the car is on warm starts the vehicle sometimes drops low in rpms and shutters. The rpms spike back up and is around normal idle rpm range. What I did realize about this is every time I get a new oil change it stops doing it for a bit. Once the oil gets ran through the motor a few times it starts back up again... However once the car is running and driving it drives amazing and let me tell you stratified knows what they are doing! Still trying to figure this out and if a oil catch can, oil cooler or a pcv plate kit will help.
