My truck recently got head studs 190/stock warren injectors and some 6.4
Banjo bolts. It idles fine at about 690 rpms bit when im driving the truck doesnt want to come down from about 950ish until i hit the brakes or let it slow down for a long time. Then will return to normal idle. Also the truck has a long crank. Like 8 seconds and other times fires right up. Ficm is good. Icp shoots up over 500 right away. I have quick tricks tuning for this set up as well. Is this a tuning issue or something else
Thanks for any help
