Bout ready to purchase 3port but I see once it is swapped out I need a tune for it to work properly and to keep from over boosting. Anyone here use it and now how much the tune cost to do this ?

 

Most tuners charge 500 to 575 dollars for a tune if you have never been to them. Keep in mind they have to put your car on the dyno , strap it down and reprogram the ECU . If you already have a tune from someone you have been to before they will generally charge you less for a retune.
