I've been getting about 260 to 270 miles in full tank of gas... :(

Am i too heavy footed?????

That 260 to 270 are from full tank of gas to when the light comes up in combination of city and highway driving.... I'd say 35% city and rest in highway.... so I guess it's roughly 14.5 gallons or so.....

Please post miles you get with full tank of gas.....

Thanks......

yah, that sounds about right- especially if you drive hard. I used to get similar gas mileage with my intake setup.

Now, I'm lucky if i can get 210 miles per tank

You should get better gas mileage with the SRT.

Welcome to the club? One reason I bought the SRT intake was because of better gas mileage. I guess IS300 and Good Gas Mileage is an oxymoron.

One difference between the IS300 and some other car is our ecu. The ecu forces you to use an A/F computer because it will throw lights when the A/F changes beyond a certain point. Therefore, since the intake adds more air, we use a piggyback or SAFC to add more fuel. So, now you are adding more fuel to keep the A/F near 14.7:1. I think it would almost break even on gas mileage. On a non OBDII car, you don't have to add the extra fuel and can run a bit leaner because you are not worried about throwing a CEL. I think this has a lot to do with the bad gas mileage still with an intake on the IS300
