Hi, I’m Cary and I’ll be helping you today.
Please understand that I can't smell, hear, or touch the vehicle, so patience is appreciated. Before leaving the site make sure and leave me a rating. You can still reply to me as many times as needed, even after the rating..

How does it run driving at road speeds?

Also, you must have a scan tool? You say the injectors go from 5 to 15-20 milliseconds.
