i get 8-9mpg...no matter what. stock converter.

 

what the hell? I get a minimum of 330 to a tank, depending on the gas station. After a long trip, my next two to three tanks are over 400 per. Granted I do a lot of highway but half of that highway is in bumper to bumper traffic, so that doesn't really count.

Oh, and I have P&P 317s, cam, built trans, 4.10s, AWD, and a 3000 stall. By all accounts, my gas mileage should be just as shitty. Just lucky?

 

I just put my 3500ish converter in a few days ago and I already notice the decrease in mpg from my oem TB verter. Went from 12.5-13.5 to 10.5-11.5. Mixed driving, mostly city tho. Hopefully it doesnt get much worse than that.

 

I get between 450 to 500 miles a tank, but I dont have a converter. I say get your tune leaned out and adjust the lockup speeds some.

 

Does sound like you need a tune up and quick.. after I tuned my up I got much better gas mileage

 

I exspected worse gas mileage but not this bad, seems like alot of you are not getting much better, I got motion427 looking at it today see what he thinks, then Im going to forward the info to wheatley

 

interesting... I have been paying alot of attention to my MPG lately...

here is what i get
15mpg mixed driving...
10mpg city driving
22 all highway

that is on the stock OS, so no lean cruise.... I used to have lean cruise tune loaded that netted about 2mpg more, but the throttle response was a little lack luster...

Also my converter is insanely loose, medium acceleration my rpms jump right to 4k... It is a bitch to keep my under 2.5k, according to my scanner anything over 2.5k is single digit MPG....

 

With my latest upgrade, I'd say I get over 30 mpg now

 

PAY TO PLAY

 

it also seems that my converter is very loose which would explain alot of my gas mileage issues, mpg usually isnt a concern but what I was getting was a little ridiculous, Im confident some of the issues will be sorted out soon
