Just wondering whats ur guys mpg with your TC.
I'm getting crappy milage (250miles to the full tank)
Does that seam right or is there something wrong with my car

 

i don't know about the gs3, but with my gs4, that's a bad number, i get quite a bit more than that, at least 300.

anyway, that depends on how you drive the car. i notice that if i gun the car, the gas goes a lot faster than before. but if i just drive it like normal, it's the same

 

That is only 15MPG... Woof.

I am checking mine on this tank under non perform Trans setting.

 

I always got 250mi per tank every time I filled up. After the TC removed, I now get 275mi/tank. So the TC makes about 1.5mi/gal differences than stock.

 

oh i forgot to say, mine is mix driving. i notice that if i drive on local, getting my foot easy on the gas makes a huge difference

 

Yep...the more fun u have, the more gas the gs will drink. I've gotton as bad as 15.5 in mostly city driving and average 17 in mixed city / hwy. Its hard to drive slow

 

indeed! when i was driving the is300, every time i get into the gs4 i drive like mad, and it only takes a quick while befre i notice that the amount of gas i burned

now i am driving the gs4 every day, i start to baby it a bit, but still, it's very hard

 

For me, I drive my wife's es300 a few weeks at a time to balance off the miles. So when I get in the gs on the weekends, all I can say is and can care less about mpg

 

even if i ease off on the gas it is still ABOUT the same not that much difference
i should hav gottin a 400, Less hassle with horse power issue

 

yes you shouldve tommy....hahah ill save my jokes for when i see you later LOL. BTW for the record when i play too much i get 8 mpg. easing off the gas brings me to CLOSE to 14. like 13.7 or something. basically got 8mpg when i first got my SRT ECU and was "testing" it. i cant wait to see what ill get when my ..... i mean my plans are done.

 

hahaha, same here, that's why we had to get gas every time i visit her... to the point that she said how about she drove so we dont' waste anymore gas

 

well, you gotta pay to play

 

you know what you should just do that aristo engine swap tommy. save you MPG and increase your power. not to mention upgrading already turbo engines is cake compared to trying and turboing the 400 motor. plus you guys have more workspace to shift around your turbo's. so, 300 isnt such a curse. sometimes i wish i had a 300 so i could just do the swap and satisfy my HP craving.......key word sometimes

i love my 400

 

Butt-out Vianh

 

Yep, I get a bit over 15 MPG in mostly city driving. And I expect that to go down a bit since I just moved to 3.76 gearing.
