Regarding flash. Do I send them physical ECU? If so it will cost a lot more than doing it locally
yes you send them the physical ECU and you list the mods you have on the car (intake, exhaust, HFC..etc). they will send u back the ECU and have a tune on it . since u are over seas then it might be a few weeks or month before you can get it back. your car would be without and ECU for a while. but that tune might help you on fuel efficiency but also on power.

Just a note. I don't want to sound like cheapskate because I know that performance cars use a lot of gas and thats understandable for me. My point is, I don't want to have lower MPG than it should be.


Regarding ECU shipping, I don't see much point but thanks anyway. Flashing generic program with 500$ pricetag (300$ flash and I assume 200$ for shipment) is way too much considering I can do it locally for 600$.
