well, i havnt taken acurate mileage results with my Current FC, but my old Red GXL avaraged 16.9mpg with City and Hwy Driving, BUT, I also had low oil pressure, running on the warm side and wasnt in good health in the first place. Combined with me shifting at low RPMs and every once in a while beating on it...

My gas gauge was crap but I filled up at around 250miles per tank...

What Aaroncake had on his site made since, shifting at 3500-4000rpm and keeping a light load on the engine and preventing the secondarys from opening up... I now do that and it seems to be better(and if not, little more driveable...) AND im willing to bet my fuel filter is cloging up... so after I replace that, Ill try and get some acurate results asap...

 

Woodstock, somewhat near you.

Georgia's gas went from like 2.09 to 2.49+ in less than a week .

Anyone with a TII that actually gets good mileage a few Q's: Especially Karack haha
1. How do you drive?
2. Mileage
3. Year

 

i fill up at 210 max! cit and highway put together on my 91 n/a.

 

70mph is about 3k on the tach in my 91 Turbo.... I don't know for sure but even at 85 I'd imagine you're not dumping as much fuel as you think. On they highway I get 22 easily running the speed limit or better and it's usually better. Same for my 88 Vert but it has a lower gear in the rear.

 

the secret is the standalone, and leaning out the cruising ranges.

I wonder what the best mileage can be gotten on stock ecu?

 

On my 88 TII with the rtek 1.7/720cc secondaries/RB catback, on a 340 trip from my old house to new house avg 60-65 mph i got 25.8 mpg!!
