$4.10 for premium and 91 octane flash tune

I have the diablo 91 oct flash I'm getting around 18mpg with a 50% mix of highway and city traveling. Does the flash tune help with gas mileage ?? Will I get the same without it??

I'm running a Brenspeed 93 Octane tune and under reasonable driving, I'm seeing a 2-3 MPG increase.

Yea that's impressive. I drive like a maniac and the lowest I can get it to is 15.5 mpg. I can get 22.8mpg doing 80mph sitting at 3000rpm the whole way for 2 hours lol. If I did 65mph I'm sure that would be a fair bit higher.

Oh and it's 4.95 a gallon here for 91 octane...

Yea I'm sure at 65mph I would be close to the same. The 4:10's don't help either. And yup $5+ a gallon for 91 here in canada.

I took a 600 mile road trip last weekend; the first long trip with the 91 octane Bamachips race tune. I averaged 24.5 MPG and I was definitely not driving to maximize fuel economy. I did about 75-85 mph the whole way, with some short bursts of 100+. Not bad...

Hmm, well around town (not city, but "metro area"), I get 12-12.5mpg.. This is with me accellerating at 75% throttle about 75% of the red lights (and being behind cars about 25% of the time). During the work week, I drive about 2 miles "town with lights" and 8 miles interstate each way to work, and I average about 16-18mpg..

Maybe my cars a dud..

I don't think your car is a dud at all man.

I recently moved to Houston from Los Angeles.

In LA I got about 12 mpg. Here I get about 18 mpg.

I think there is a VAST difference between what people consider "city" driving.

DC Metro, LA or NYC... those are fairly the same I would suspect. Most others.... like where I live now in Houston... it's just NOT the same bumper to bumper grind.

You obviously don't travel US 290 (NW Freeway)! I travel 10 miles and it takes 30+ minutes. But then I get on BW 8 and the next 15 miles only takes me 15-20 minutes. I average about 16 MPG on this daily trip with a 93 race tune.

Like I wrote... in LA I got 12 mpg and here I get about 18 mpg.

Is there traffic here? Yes... is it like Los Angeles--no way in HELL.
