hey all, I'm almost certain this is a repost, but since search function is no good at all i can't find the previous larger thread. I was trying to see the MPGs people with FI setups were getting. I remember being suprised when i saw people getting 35-40 MPG and pushing 300whp.

I'm also trying to figure out how this works if anyone can shed some light??

 

doing 65-75 with occasional boosting, i saw 27-29mpg. at 85 mph with lots of boosting i got 22-23mpg

 

in city traffic usually 19-21.

boosting pulls all day = 18 mpg

I've never seen anyone get 29mpg on a turbo setup, ever...I'd say thats off. 25mpg at the most.

 

I get like 2-3 blocks to the gallon

 

LMAO you must be lyin then Soul

 

i have made a log of every tank of gas i have filled up. On cruise control, with occasional boosting i got 27-29mpg going 65-75mph on the highway. It is all in the partial throttle tune, there is nothing out of the ordinary to believe that under vacuum conditions you can't get that MPG. I would advise that you get a different tuner before you say 'it can't be done'!

 

When I went on the Boston Mountain run, I was boosting everywhere. While everybody had half a tank left mine was at no bars. I had to coast in neutral because I didn't know where the next gas station was going to be. When we ultimately stopped at a gas station, I filled/used 11 gallons and we had been driving for ~150miles. ~13 mpg... boosting ALOT

*I have 4.44 and no yellow box, so its off by a bit.

 

When I drove from PA to Chicago in my S I saw about 25-27 mpg and that's with gears. I saw only about 1-2 more mpg stock. Of course this was with no boosting. Except once......man that minivan didn't see that one coming!!

 

Driving conservatively on the highway with little boost I get 15 mpg. City/lots of boost I get around 9-11 mpg.

1000cc injectors, walbro pump, and aem 1:1 fpr.

 

Sorry unless my speedo is way off i have to call bs on that one. If im CRUSING with the cc on at 55mph i have seen as much as 35mpg, but i still usually get around 28-29mpg. At 80-90mph its about 24-27mpg. Daily driving i get around 20-23. Driving hard on low boost i get about 17-18... on high boost its about 13.
