long story short, found my stock jtech pcm is going bad. Had crank no start. Found I have to turn key on, leave it in on position in order to “warm up the pcm”, then proceed to crank it over.
Now my question is, my engine is built (heads, cam, bored 20^, headers) and I already had the stock pcm tuned via sct. Is it worth spending money on the mopar performance pcm? Or get another jtech and tune it again
Second question, would the MP pcm learn and adapt to the mods I made or does it need tuned for some mods?

Get another one and custom tune; your original custom tune was tailored to your specific combo. The MP PCM is designed to enhance a stock engine. It might adapt to freer flowing heads but it would not adapt to a cam change.
