Fuel economy and improving it, among other things.
I just made a 225 mile test run today with my 2.0 l turbo in a MKI with a FO
trans. 3.89 final and 0.71 5th .Half of the run was with the A C on. thanks
to Dan's mega squirt tuning I got 33.4 mpg.most of the drive was around
65 -70 mph with a few short bursts to ????. I still don't have any low Kpa
numbers (50 and above).I don't have any apparent Vacuum leaks. The engine
runs real strong so I don't think I have a basic engine problem.Any ideas?
