ok so im going to port my supercharger before college starts back up (august 25th). haha im getting a reasonable street tune by playswitcars in mid july hopefully. my question is if i just do a modest, nothing crazy, porting of my blower, will i need to get retuned? I will be running on the leaner side after the port correct? thanks guys

 

need, no. Should you yes. After we installed mine things were a little out of whack and the re-tune made it all better and you might and should be able to squeeze a little more power out too

 

You don't NEED a retune. The MAF still knows how to calibrate for the airflow. BUT the cars can use a MAF calibration anyways.

 

ok thanks guys
