the windshield mount is junk. I could not get it to stick even if I made it wet. They should come up with something better.

Tuner has very good tunes an abLe to upload custom tunes via download or micro chip. Can't beat this tuner the Trinity customer service SUCKS!! I emailed them asking how to make the tuner to power down once the ignition is turned off after 4 days I got a response from them, all they said is to unplug it from the ECM port. When i mentioned wanted to use the gagues feature while driving the CS Rep came back with "sent it back where u bought it an get a refund then". That isn't cool at all.
