What?? 22mpg freeway and 20 avg on E85 and boosting? That seems too good to be real. I really hope your not using the on board mpg readout from the car. That thing will be WAY off. It works off of the amount of pulses the injectors are making and not real time data. Your 1000cc's are spitting tons more fuel per pulse than the stockers.

FYI. I was getting 12mpg in town with E85 in my 350z. I cant imagine this car is that much more fuel efficient. Even on 91 octane I am getting 18 mpg in town with my 370 and 22 on the highway.

I was shocked myself. I am pretty sure everyone knows the readout is useless once you change injector size. I used the trip odometer and full tank to full tank minus fill to determine this.

A little more detail:

I had a 2gal gas tank with me, filled half way.

Whole trip was 393 miles, of that:
*~50 in traffic, literally 2 hrs of traffic: avg speed 25mph
*~30-50miles in 2-4th gear, usually about 10psi. This was the San Luis Resevoir/152 gilroy approach. Real fun drive, can get into it, turn and all that. RADAR DETECTOR A MUST, but very easy run, meaning you can go apeshit on throttle

At refill i put in 18.4 gal, meaning I used 18.4+2 to go from full to full, therefore i used 20.4 gal for a 393 mile trip.(Don't mind me, I typed this out *** backwards earlier)

393/20.4= 19.3 mpg. Now I am saying highway avg speed 70, I wouldnt be surprised to get more, hence the claim. But 19.3 is amazing. I was expecting 12-15 at best. Mind you, this is the first outing with a brand new TT installed, so one can assume I am not driving for MPG and you would be right. IF i tried, it would be pretty neat.

I am going to say that my tune and fuel setup are doing a great job. But to say everyone would expect 20+ is a lie, but apparently this car is there. Remember, it was cool and clear last night, so may be a best case scenario, but this is what I got for the trip.

Lets not get caught up in MPG, the car rapes apes. I merely mention it because alot of us are going e85 and I wanted to share how I feel about it so far. Just took it to the bank. OEM DD capable indeed! It is moist out, but I managed

The CJM kit is holding up perfect. Those sexy blue rails, Fuel Pressure is rock solid and the car pulls smooth from 0-7000. Seb's tune is amazing thus far, the man knows how to do e85 and am happy to have his tune on this thing.

While the response is very "cliche", I think anyone is justified to say what they want, how they want. Modding a car is not groundbreaking, we shouldn't expect everyone's response to it to be as well.

Well, E85 here is only 2.89 a gallon. If I can get close to 17 mpg I would actually be saving money at the pump. All that plus race gas safety with a cooler charge. Win win win.

Very impressive btw.

Yeah. It just doesnt contribute to the knowledge of the community when 95 percent of what some people say is their "opinion", which is mostly negativity, versus facts and data.

Not yet. Was planning on doing some today but it's a tad too wet to want take the thing out.

Will definitely do some on ramp 0 to 60 four funsies soon enough.

Here it is noobs....

Ignore the warning (tire sensor)

This is 91.

Running TT, Going up to 180MPH and Down to 50MPH, 60 Mile Run in Total. From Fontana to Sylmar. This is what I see when pushing the car hard (but not too hard, shifting around 5500RPM not 7400RPM)

That's Right, 26MPG Boosted! Fast Intentions Turbo Kit is SAVING ME MONEY! LOL I was never able to get this on N/A running car this hard.

Lol, you can't use that. It's not close to that because your injectors are so much larger. Sorry, but you're the noob right now

Exactly right, that thing measures the fuel injector pulses not actual mpg.
