I have SSTT and since I put it in my mileage in town is 16mpg. I drive spirited about 25%. My Titan gets 14 in town.

Possibly an effect of only adding fuel and not controlling timing? I am averaging close to 400 miles a tank on a mix of 50% highway and 50% city. This would be an intersting comparison between the JBV2 and the other piggy back units.

[HyperM3]

How many miles do you have on your car? When I first got mine I was averaging 17mpg. Then after it broke in and I started shifting differently (1-3-5 only) Ive been getting 22mpg. This weekend driving down to VA I was averaging 28mpg. This is all with PROcede on.

Interesting, I've never tried that. By the way, with the Procede cruising has improved, but playing has cost me approx 2 mpg.

There is no way that you can get 400 miles on a tank of gas with a mix of 50% highway and 50% city. Unless, you're driving at 60mph on the highway 100% of the time.

I get around 18mpg with spirited driving. If I drive like a grandma with mixed driving, I get about 22mpg.

Yeah, that shifting technique especially with the torque of the PROcede works wonders. I find sometimes that when I play, the mpg actually goes up and/or stays the same. I dont really get on it too often though since Im in traffic most of the time.

If? I only saw you driving like a grandma this past weekend. I think when I drove your car it finally woke up and was like "What the hell? Is this what Ive been missing?".

Call bullshit all you want I have no reason to lie. 22 mpg must suck for you.

Not my experience, there has been no significant change in mileage, a drop by 1 mpg when driving aggressively. At one point mileage actually was a little better than before putting on the JB2.

[max boost]

wow....i must have a heavy foot!
14.8 here

[Acap14]

I have procede and i drive to Wv alot to go see my girl and thats 370 miles from my door to her door and cruising at 80-100 i get there on one tank of gas with like 30 miles left on my display. around town i get like 16 mpg but i DRIVE it.

[NYCGarbagePrince]

Please for the love of god tell me you didn't buy a software tune with the only intention of getting better gas mileage. Not to mention it should be assumed that when your ecu is being tricked into injecting extra fuel due to your jbs2 it will tend to use more gas. Only logical recommendation is to drive less. Or remove it.

Next time lend me your V1. lol! Plus, I had to make sure the other guys without Nav could keep up with us. Not everyone has a V1 and Nav, you know?

I'm not saying that you're lying. I'm just stating that you're merely delusional.



50% city and 50% highway and you state that you can go 400 miles on 1 tank of gas? Unless, there's no traffic in your city driving and there are no lights and you don't need to stop, then yes I believe you.

[Sniz]

I've averaged 23mpg in my 6MT procede equipped beast. Trust me, I dont drive slow. My rear tires are all the proof I need to prove that one.

The great thing is that w/ the TQ procede offers you, you simply dont need to rev high if your cruising and passing at will. I typically rev to 3k-3.5k in each gear and barely use the gas. i still laugh everytime I leave a stoplight and leave everyone behind and yet I am BARELY using the cars power.

So me driving + procede = 23mpg

Not bad at all

[leftcoastman]

On an all highway trip, averaging 80-85mph, I got 34mpg - with PROcede.

On track, I'll be lucky to break 8.5mpg.

It can't be true anyway, your display is lying to you or you are really getting almost 25MPG:

22MPG * 16.2Gallons@Tank = 352Miles

400 miles / 16.2Gallons@Tank = 24.691

Remember, everytime you fill your tank the miles to go pumps up like crazy.
Mine is pretty accurate with the MPG, I also measure by dividing the trip miles to the #of galons I fill it up with, very similar to what the car tell me.

My last trip to orlando with Pv1.47 it said 23.5 and I actually got 22.5, I was going very fast, did over 130-140 many times. in my way back it reads 24 and I did get 24 but this time I cruise more like in the 80smph with few 100smph.

After getting the procede my mpg when down 2 to 4MPG, I'm getting high 16,17 and casually 18MPG, i can't control my foot, I just love the acceleration... :happy anim::evi l:

I did not buy this thing planning on getting better gas milage.. however when i had my audi chipped i got a little better gas milage with it... but that was driving very easy... yes it tempting to nail it but still

+1 If you one more power, guess what, more gas consumption. there is a little exception here, since this engine are TT, but hey dont expect improve at all if you dont want surprises.

[Jonmartin]

I get about 19-21 mixed and I boost virtually every chance I get. with Procede 1.47

[Beer Goggles]

I average 22mph with JB1...timing control has nothing to do with MPG...use your right foot.

Anytime you add boost you add fuel, which means you use more. If you really cared about MPG you would have bought a 328 or left it stock.
