I got mine done at the Active Green & Ross on West Drive just S. of Hwy 7 for $153 after taxes yesterday.
They ran it for an hour and I was able to see the car after a stop at the Tim's across the road to pass the time.
Considering my UIM & LIM were already clean I didn't notice much difference (maybe a wee bit better tip-in on launch). Will check the promised mileage increase over the SVTOA cruise this afternoon ... although that may be a bit skewed by my driving considering I do like to lead "spirited" cruises
