Vq35hr ecu reflash question
 

i'm thinking of reflashing my ecu .. now correct me if im wrong but reflashing an ecu isnt the same as doing a full tune right? .. i have the jwt dual pop charger and ART pipe set up .. for now .. i'm goin to get a custom exhaust later in the week .. now my main question is .. is it worth getting a reflash done and getting a tune later? .. i read that reflashing helps your mpg a bit so i wouldnt mind saving a gallon or 2. also read that it makes your car run a bit better. My Z is running lean ever since i got the ART so yeah ..
Does anyone know who does ecu reflashing in the portland area? and what would it cost?

I do. I'll PM you

A reflash is usually done during a tune. Depending on what system you're using and what you're trying to achieve, a reflash may not help MPG. In fact, if you're tuning for power and using higher octane fuel and max revs, mileage can really drop.
