    Default CSP Tune Changing Tune Position On It's Own????

    Has anyone ever heard of a CSP tune just changing tune positions on it's own? Got a truck that for some unbeknownst and bewildering reason is changing it's tune position up to switch 4 position. Flash the truck and without the CSP switch plugged into the OBD2 port it'll be in tune position 1, turn the truck off and start it back up and it's in tune position 4. flash the truck and plug the CSP switch in and it will ignore the switch position and just end up doing the same thing, be on switch position 1 till the truck is shut off and restarted and it'll be locked to position 4.
