Your best bet is to return the needles back to factory and re-tune. Tune your HSN first, once you have that right then start on the LSN. Put your temp gun away. Some engine prefer to run hotter than others, you can't tune by temps. My V-Spec is a bit of a dog at 225, which some would consider perfect temp wise, and hour leaner on the HSN puts me in the 235-240 range and the engine screams!
Also keep in mind to NEVER tune until your engine is warmed up for at least 3 minutes of hard running. You have to get heat not only in the engine but also in the chassis. An engine will lean out at bit as it comes up to temps, so where you may have a perfect tune when it's still cold, and once it heats up all of a sudden you find a big loss in power because it's over lean.
