a warning about a Giles pump. The added power and smothness make it hard to keep your foot off the throttle. TOO MUCH FUN!!! lol
I have a 1.6TD super pump in my 78 Scirocco rallycross car, geared too low and only gets 47mpg cruising.
I also have a Giles worked pump in my 98 Jetta TDI daily driver. regular commute = 48mpg but I did hit 50 last fill up. This is without trying at all and going with the flow of traffic.
your millage may vary
