Had this RCSB 5.3L/60e.
Cam, heads, header, CAI.
Most of the time I want to wot from stand still, or rolling at low speeds it just flat out and eventually (seconds after) start responding.
There is stock stall, and head/cam is patriot universal combo !
I notice in the log that sometimes timing falls to 1 degree. like in 1800 -3400 range briefly and without any apparent reason !
Hope someone can take a look at the logs and give me a clue.
