i bought a new Trinity i followed all the steps for the updating and its done , but when it comes to install the software in my truck its pup out a message that says :'' your calibration is not currently supported. Trinity will try to save your orginal back up'' . and there's some Troubles cods is came out on my truck such as engine power is reduced and check parking sensors ect... so i toke it back to the factor software
