2004 Rpm dips out of first and out of R
Hello all, new 04 owner here. Bought a full bolt on 5.7 and only issue I’m having is an RPM dip when first starting a drive, after shifting out of first down to 300-400 and also in and when shifting out of reverse. Car always recovers after first(although doesn’t always feel like it’s going to) but has died when shifting out of R. Idle is steady at 1000-1100 usually. Not throwing any codes, visually checked/tightened up vacuum lines and CAI connections. Thought may need to be re-tuned but wanted to see if there was anything else I could check before.
