When my car was pro-tuned a month or two ago... he loaded a few maps for me. One of those was an "economy" map which I never tried until yesterday.

I was always wondering why my mileage seemed to be crappy, even on the highway at cruising speeds... it's been that way since it was stock day 1. My best average cruising to and from work (20 miles 90% highway) was about 20. Seems no matter what I did, I didn't change the MPG too much. My usual average city/highway mixed is around 18-19MPG.

I drove to Vegas yesterday (here now) and I wanted to load the Economy Map from HB for the drive over. Now, granted the power and "fun" factor obviously goes COMPLETELY out the window...

250 mile trip, I still had 1/3 tank left! My average for the whole trip was 24.9MPG!!

I gained almost 5 MPG with this map loaded, on the highway! Considering this was up and over the mountains to Vegas too, that's pretty darn good! I think I would have been higher, had I not had the long mountain pass climb for about 20 minutes. I'll do it on the way home too, and compare both directions.

In any case, if anybody gets a pro-tune have them load you an economy map for your car... it can definitely make a difference.

That drive is always horrible going to Vegas since it is uphill most of the way. However, you should see 26+ on the way back. Looking forward to your results.

Also, did you use the cruise control as well? If not, try that and I bet it goes even higher.

I love that hill coming down about 20-30 min before you hit vegas.
It liks all downhill coasting for like 10 miles

Put a few gallons of 100oct in it for the return trip and see what happens.

what was your cruising speed?

i went to san fran a few weeks ago, and averaged about 23 over the coarse of the trip, went up to 25 when going down hill for a bit. i was cruising between 75 and 85 most of the time.

Ok guys...

On my way back I averaged 24.6, so basically the same... can't complain! It sure makes a big difference in range, even from 19mpg to 25mpg...

That's awesome! Tidbit of info comes in handy for everyone on these boards even though some of us are running 850-1000cc injectors.

i drove up to cambria for the weekend and got 28.997 MPG on Jons map..

i didnt get any economy map.. from what i understand, any time youre running under 2lbs boost, its economy. after that bets are off.
