I adjusted my alda about a month ago and have not seen any difference in fuel economy. In this time period, i have made a run from Houston to Florida and back and a trip to Florida and back. I also drive stop and go traffic every day on I-10 in Houston...no difference in mileage. The performance has increase dramitically though. I am still not reporting 0-60 times like others on here but she is definately faster than i tought she'd ever be.
