My rig seems to idle high (too fast). I've followed all the advice I've received so far and nothing changes...still fast idle. I took a look at what IP I have installed currently. Looks to be a DB2381-5485, part# 12561514. From the research I've done, that IP belongs in a 6.5 turbo (98-00 HD military turbo, 1.2CST, 200HP). Could this be the cause of my high idle? Will it hurt to leave it? Other than fast idle, it runs great!
