I have a 2006 Mustang Gt with the JLT II Air intake installed and tuned with the SCT II. I am thinking about installing a Billet Grille Overlay both top and bottom and was wondering if anyone else has done this and needed to retune the air intake due to restricted airflow or if they have had no problems at all. Thanks.

 

I have the TI with Brenspeed tunes and noticed no difference when I installed the overlays.

 

Thanks unsocbl! by the way your grill looks great on that car especially without the emblem.

 

No flow problems, you'll be fine.
