I am a professional technician and have been in the business for over 40 years. I can't report anything on fuel mileage because I haven't gone through a full tank of fuel yet. There is a noticeable difference in throttle response, it's not as restrictive as it was before. I also noticed a mid-range difference which will help when pulling my trailer. The local Nissan dealer stated that the modification will not void the warranty if you follow the instructions properly.
