from what i understand, the reason your car leans out after a week is due to the oem ecu trimming the fuel for whatever reason, ie weather, altitude, etc. On a dyno its hard to predict this unless a very good tuner compensates for it. At least that is my understanding from my hours of research. By the way I just got my aem ems from the brown man today whoohoo

 

at the very least get a emanage ultimate and a proper tune..

the blue doesn't belong in a FI car

 

not to start anything but I've been at least 7 months running great besides a rich cel that I awhile back. 14-14.5 at idle 14.5 to 15.5 part throttle and 11.5-10.5 at wot.



D.

 

Whos the brown man? haha is there anywhere to buy the ems that is priced half decent?

 

oh you know the brown man with the brown truck who likes to race in nascar hahah. by the way got mine brand new for 1200 shipped from gruppe s

 

exactly what i was about to get to. sometimes i think the newer generation of cars are getting to smart. Hopefully i get aem ems soon

 

The blue, vafc, and neos will do this over and over again. The E-manage Ultimate will not along with other systems like f-con pro, k pro, aem ems, etc.

Again, get rid of the blue especially if you
