I have a 2018 GT Active exhaust with a JLT CAI with the plastic tube. I also have an H pipe installed. After installing the JLT CAI I used my SCT X4 to program the car. I selected 93 octane and JLT CAI (plastic tube). All other settings I left stock. Now the car has a vey slight rough idle and also feel that when I accelerate. Its not very noticeable but I can feel that slight sputter when accelerating. My question is, do I need a more detailed tune (map) since I have an H pipe ? I did this same exact setup on my previous 17 GT and used a different SCT X4 to tune it and never had an issue. This is a different car, a different CAI and a different SCT X4.
