Thank Mike. I’m also new to the Fitec. As far the truck I bought it from an Army buddy of mine. Been wanting it for several years. He did the truck then parked it so there was some fine tuning issues that had to be addressed. If the truck sits the Fitec has to relearn all the info from the motor. What it will do is immediately start and go to high idle. It will go back and forth several times the settle into a normal idle. When you drive it the motor will go up and down in idle for several miles then settle down. From there it’s pretty good. Now, if you want to fine tune the programmer allows that but better to have someone with one skills do that. At least for me.
