I agree, I've had one on my 17 GT for 2yrs and have no issues The upgraded performance is worth every penny. Drivability is spot on. It also tweaks the auto.I had one on my 2017 GT for about two and a half years before I traded it in. I had no complaints, deffinetly felt an improvement, especially in the lower rpm ranges. Install was pretty straight forward, just take your time and follow the instructions and you shouldn't have any issues.
