Another satisfied customer here! My vf40 needed to be replaced and I found a good deal on a vf52 so I went ahead and went from stage 1 to stage 3 over the 4th of July weekend. The car feels so much smoother and the power is awesome, even on stock fueling. I also averaged 25.6 mpg on my way home from Cincy that weekend. The TA team is awesome and very fast getting your maps to you!
