When she drives an entire tank, it's about 20mpg at most.
Update v. Car is Now Running A Haltech.
Subject car is an 04 MSM, RC 550cc injectors.
Highway best of 33mpg, we've hit upon an average of 30mpg all highway, about 22-24mpg around town. Obviously when raping it, the numbers go down a little.
At this rate, the Haltech will eventually pay for itself due to improvement over Hydra.
Now that said.... let's get stupid.
My daily driver MX6 "tuned" on band-aids has achieved a best tank of 41mpg on the way to the GRM $2012 Challenge. Typically gets 35-37mpg all highway, and about 31-32mpg mixed.
So... that's pretty awesome.
MSM runs 14.7-14.8:1 at highway speeds, MX6 rapidly cycles between 14.5 and 15.1.
