They make so many styles I will check for a box, most differences are gimmicks. I can check the battery voltage with mine! Same red control box though. I have used PLX devices for over 15 years. Very high quality. With the software E/C provides we car datalog but it is slow to react showing high boost only at high rpm's not at 3000rpm when it should show full boost to my knowledge of SC's.
Mine is a digital read out and I don't think mine shows vacuum. They are all good units, just want the latest one and I think that is what i have and will confiirrn tomorrow during the day. mrk Did you get the link to the injectors I bought? Price nearly doubled but they are Bosch and have the slots to accept the clips should you choose tom use them. As I have stated my O-rings were almost shot, very stiff and ready to crack. When you get to that stage let me know and i will let you know what i ran into changing nthe inj's, mark
