HORRIBLE GAS MILEAGE POST RECALL (ಥ﹏ಥ) ¯\(°_o)/¯ - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

mswbrz · 08-02-2019, 01:10 PM

What type of are people experiencing post recall ?
I go have Fi and after the recall my gas has been total shit in town, I'm talking bout 16-17 mpg . I'm about 1000 miles post recall and thankfully haven't had no issues with the recall but the car was over heating after the recall. On the highway the mileage does go up but I don't have the figure to share .
I'm hesitant to want to take it back to Subaru of Modesto as they had the ride for over two months after the recall for an over heat issues that it never had before before recall , the car was broken into in that time aswell and the experience was a nightmare just to get my car back.
Engine Mods :
She has jrsc / delicious tune
Ace headers 421,
Invidia mid high flow resonate mid pipe
Gretty exhaust .
Any shares or thoughts on helping I would be appreciated ᕙ(◉෴◉)ᕗ

wouldn't take it to a dealer, find a good tuning shop in your area or the actual person that tuned your car in the first place.

Nothing they would have done "should" have impacted mileage. Not like they would fix it for free anyway since it is tuned. As Why said I would get your tuner to check it over.

Sounds like they didn't put a vacuum/boost line back correctly, go over the jrsc install again and check intake manifold fittings as well as maybe the O2 sensors on the headers.

Are you able to do any data logging? Wondering if there is anything there that may tell us more (like the car running rich)

I had mine done where I bought the car, Toyota of Louisville. The guy that did my work is a motorhead with a pretty seriously souped up MR2 and his brother owns a turbo charged FRS that he did all the work on. He does all the work on my car and it's been top notch.

As was the recall work. I'm not normally a fan of dealership shops but this place is the exception - at least for me.

100% this, plus get some data logs to see what's happening.

I tuned the car myself via ecutek and delicious tune , I can do Data logging and send it to the peeps over at delicious tuning ,
In terms of a vacuum line it doesn't feel any less power in terms of boost , would i notice a difference in performance ? No cells have popped either in regards to loose 02 sensors ....

Would this cause any feel in any less performance , or any cells to pop ?

Depends on which one and if it's attached at all or just a minor leak due to not tightening all the way or something.

When I see mpg decreased, it always comes with decreased power. All of them were related to air leak, vacuum leak, of dirty MAF ... well, other than very hot humid weather.

Most serious leak I had with JRSC was the leaks from the solenoid lines under the intake manifold. You need to clamp both ends of both lines connected to that solenoid. Highly recommend trace and clamp those.

mrg666 · 08-02-2019, 06:09 PM

Oh another; if you have installed, make sure oil catch cans, especially PCV, are not overflowing or leaking air from the cap.
