Purchased the Edge 83830 onboard monitor,cool thing it plugs in your odb port 2 and monitors your vehicles performence statistics,such as boost psi,iat temp,o-60,1/4 times etc,only thing i need to order a longer extension and do a little fabrication so i can install in the head rest by the glass holder comartment,fits perfect inside,i can open it and close it and most importanly.dont have to leave it by the windshield for various reasons.
