Question about tunes

Hello, I am new to the forum and I recently purchased a 2010 track 2.0t, I absolutely love the car. The only modifications that I have is a full magnaflow exhaust and tomorrow I will be putting on a spectre air filter with the silencer delete. Hopefully soon I will be getting a downpipe and a tune. More to the point, after searching around the internet along with this forum for a long period of time I still am unable to find the answer to my question, which is if I had an ECU tune, for example poweraxel, and perform a performance tune, around how much MPG are you guys losing? I know everyone drives differently, but just a ballpark number of decrease in MPG, cause the extra 30HP sounds really nice, but not if it completely consumes my milage. Another thing I wanted to throw in, would you guys suggest getting it tuned at a shop or buying a portable flash tuner that I can save my stock ECU on. Thank-you and I am looking forward to discussing the car!

I don't know, but often times you will get better MPG's with a tune.

A good tune on stock turbo can net you as good or even better mpg than you are presently getting as long as your driving habits don't change. More power has a tendency to corrupt...meaning it will create more of an itch to press that little pedal.

As far as shelf tune vs dyno tune - dyno tune wins all day since it is being done for your particular car on a dyno. Shelf tunes normally are good enough to get you in the ball park though if you can not get to a tuner, just make sure you choose a tune for you mods.

The PowerX which is what I'm going to use initially can store factory tune, but beware it is not the exact tune you had with you vehicle upon new car delivery. It will have all the same maps & values, but the encoding will be slightly different & if someone looks hard enough they can tell the ECU has been tampered with.

Hope that helps...

Thank you so much. One last question if it's not an issue, i tried but haven't been able to get a hold of powerAxel, do you know of any shops near la that have the tune? And again thank you, that helps so much
