75mm Accufab throttle body/plenum and fuel consumption MPG

[propellerhead]

Anyone see a change in their MPG after installing a 75mm Accufab tb/plenum, or any other brand? I was averaging around 17-18 mpg with the stock set up and my first tank with the 75mm intake, I'm got 13 mpg. I didn't really stomp on it any more than I normally do.

I get the exact same fuel mileage with an accufab 75mm TB, and a C&L plenum than stock.

No difference for me. Who you buying gas from? Stick with the big *******s for at least a better quality gas.

Same gas station. Same driving style. Same everything. Maybe the computer is still learning or something.

But, who are you buying gas from?

Thats horrible gas mileage man... I usually see 22.5-23.5 mpg even romping on it.

Shell. 93 Octane.

Shell. 93 Octane.

That's a good supplier (I work in the industry). Must have been a fluke or a bad shipment. Check again from that station and if still bad fill from another Shell station and see what happens. If it keeps up, try Chevron. Might be some other factors. Gas is getting really expensive so I don't put it past a station to do some stupid ****.

What could they do that could screw with my MPG that bad? I didn't hear any pinging the few times I got on it.

I'm not a gas guy but I'm a software developer that deals with their "commodity futures" that ****s all of us (but I have no control over that). I'm just saying that Shell is a good supplier. I've had bad gas before from Texaco and they are now part of Shell. They are good. I figured it was the station. It took me awhile to get rid of it. Also, when was the last time you changed your plugs?

You'll be fine. I doubt it's your TB setup. But I'm no expert.

I got 112 miles on my tank today, filled up with 13 gallons... Apparantly 3rd gear on the highway without shifting and launching from every light isn't good

acetone

try a few oz's of pure acetone , it works , look it up on-line I have been doing for over a year , no damage more power & great mpg , be carefull not to spill any on your paint 2-3 oz per full tank & you will see the change right away

 

[SigmaPride]

Didn't notice any difference with my 75mm dragon.

 

[merc123]

No difference with my 70mm accufab and plenum.

Ditto. I saw no difference in gas mileage after the install.
