Jackson, I have not had a chance to "test" it out. Prior to last night, the volt light would illuminate when the car was under boost, about 10 psi,been more of a reoccuring problem. And to honest, my eye would be on the scanmaster most of the time driving, it is actually painful to be staring at the little black box instead of looking on the streets for another TR. I'll post back any updates later. Mahalo for the help guys.
