Your car is making some great numbers with that turbo & TMIC combo.

What MAF are you using?

He is using the tube that is in the stock air box. It works great! I did the same thing when I had my LGT.

unless im misunderstanding something, the stock MPG gauge is inaccurate after injector upgrade.

Doug, how about a video of the car in action?

^ Yeah, that pic shows absolutely nothing . I guarantee you have to fill up just as often as you did before. Fancy tuning and big turbo upgrades doesn't mean you're going to get hybrid gas mileage. Although that would be nice.

The ECU likely uses injector pulse width to measure fuel consumption... MPG or L/100km in my case. The ECU has no reason to treat injector scalar as a variable. Regardless of the injector you use, the ECU will be basing the fuel consumption calculation from the pulse width of a 565cc/min stock injector. Bigger injectors mean lower pulse width for the same fuel, so "better" fuel consumption according to the ECU.

Actually my MPG reads within 1-2mpg of what I calc when pumping. Like I have said before if the injectors are scaled right in the ecu then it doesn't throw the calc off.

What are you using to tune it with?

Interesting. So you hacked the MAF housing area out of the stock box and installed it into a cold air intake type pipe? Do you have any pics?

Thanks

Here's the one that I did on my LGT. You cut the entire MAF tube out of the air box top. It took me about an hour to cut it out and get it smooth. Then I wrinkle finished it. Doug's is basically the same without the wrinkle finish. And his is on the end of his rotated turbo cold air set up where mine was used with a stock location turbo set up.

Congratulations on the new car and the awesome job on how the car is turning out. Thanks again for the killer Pro-tune on my GD Sti in San Antonio. Say Hi to everyone at the Shop and keep us updated on Roxy.

Just ordered some new parts for my ride. I am planning on running it in some local NASA events so I might as well get it ready.

So... coming soon... StopTech front and rear brake kit, Cosworth FMIC, and GSC S2 cams. I will also do some kind of lip but I am not sure just yet which one.
