Hi. Im new to the site and not sure if im posting in the right section but ill post anywhere. I am picking up a 2004 Cummins 24 Valve on friday. It has a 4inch straight pipe(i do believe turbo back) and a aFe stage 2 intake. Im wondering what a good tuner would be. Im not looking to spend too much money. i really want one that allows me to have a cool down cycle and a high idle option as I live in Canada. the truck will be plugged in most if not all the time but still like diesels to have a high idle. And has anyone had good luck with aftermarket command starts? and will the high idle tune work if it is put on when truck is shut down and then command started. thanks. sorry for all the questions.
