hello everyone,I need help.. i have a 2016 silverado 1500. i had some trans issues so while i had it built, i installed a cam, lifters, springs and push rods.. cam required a 4* phaser limiter. i was able to get the truck running somewhat ok, but its not where it should be and im all out experience. im getting a cam over advanced, and commanded idle not met CEL.. as soon as i start it, the idle suddenly dips, then gets up to around 1-1200 range while warming, it will suddenly idle up to around 2 like i hit the pedal quickly, then drops to where it idles around 700 +-.. when at running temp it seems to really pull the idle down when going into gear.. Any help or advice would be greatly appreciated. Id live to drive my truck without it feeling like a turd..
