Hey guys I've tried to do a search on mpg concerning a greddy tt kit before and after but couldn't find any information. I was curious to know if there is a drop in mpg after the tt was installed. I use to own a civic and got 35 mpg before, but suffered only 22 after i installed the greddy tt kit. I wanted to know if that was the same for the 350z or not.

 

the greddy tt kit should maintain at least the same mpg if not more compared to a stock car. gq626 said this before in one of his posts that it improved his gas mileage

so long as he didnt get on it

 

Yep, with larger injectors your gonna loose efficency. I can't really give you a number because the emanage messes up the computers ability to figure out MPG, and I'm yet to do it the old school way.

 

I dropped more mileage going from stock wheels to 19inch Volks...then from going TT. I got about 20mpg with wheels...no turbo. Now I get about 19-20 with the turbo. Very close. If I do all freeway driving, I could get significantliy more mileage.

ETX, the eManage is scaling the injectors, so under cruise conditions, you should be getting almost exactly the same mileage. My AEM shoes 14.7-15AF at highway cruise.....normal to me.

 

Yeah, But I think the computer thinks the motor is getting less fuel because of the emanage messing with the MAF signal. Thus is thinks it can get farther on the amount of gas in the tank. Mine says 34 mpg, No way in hell that is correct.

 

Thanks for all the info guys.
