Verdict is still out.
Bought to recalabrate my speedometer on my truck. It was easy to hook up but states it needs calibration. Called company they stated software was up to date take it ford and have truck software up dated. Spent a 100$ had computer updated. Hooked programer up said it needed updating. Called company they said sent it back so the could update software on programer. I have now spent hundreds with no success. This was my second jet product first one worked great this one not so much.
