I guess that gives me another excuse to buy hp tuners and probably make stuff way worse with my inexperience and ambition.....I'm really hoping to get this thing on the road soon to see what I needed to play with over the winter. Just need the MCO at this point to get the paperwork moving.It’s common for tuned lnf’s to not idle well at startup. Mine does it. I’ve dug all through HP Tuners forum without finding a real fix, although locking down the things that vary in the idle range can help. Since mine smooths out after a couple of minutes, I haven’t tried real hard to fix it.
