23.66 Mpg!

1000 Kilometers, and I had to squeeze every drop into the tank to get 100 Liters to fit in!

Checked on the way back , and for the same 1000K I could only get 98 liters to fit!


Anyway you slice it.... that's some great economy. 8 mountain passes, some stop and go Vancouver traffic, and peaked at 24.14 mpg!!!!!!

All hand calculated, at the pump. SMARTY is making me SMILE!

Level 5, RP#2, Timing 4, Turbo=Off, shift lim off, RPM Stock!


Of course I made sure so shift at 2200 rpms religiously and use Cruise control whenever possible!

Worst part was the Kootenai Mountain Pass... Water temps were 190F and Oil temps were a BLAZING 230F on the long climb side, and I wasn't even towing!

Tire pressure was 68 PSIG Cold, Airbags were nominal at 35PSIG.

IE SP62/14 Stock intake and exhaust, and the kitty is still there too!

Bob, Marco, Thanks for the help!

What kinda grade is Kootenai Mtn Pass?

We just got back from a vacation. We drove from Katy Texas to Hot Springs Arkansas and it was 452 miles. I hand calculated the milege and figured it to be 22.6 MPG. We kept the speed just under 70mph. I think thats pretty good.

Ok, now I'm confused. tnt/r is not available for download so were you using tnt or the revo. The reason I'm asking is timing #4 on the tnt tunes are low timing meant to be used with nos but the revo #4 is the highest timing level.

Hm. I might have to go out and check my revision, now you have me going WTH?


At any rate, i will stress that I was consciously trying to eke out the most mileage.

Combined with the settings, you have to practice restraint, and maintain momentum as best you can. A 10 mph headwind would have made the difference between 19.5 mpg and what I ended up with.

In terms of absolute economy, you can control everything but the windspeed and direction.
