One Update, I was having oil temp problems. I had a Stillen 19 row street oil cooler installed by the Nissan dealer. The car runs like a completely different car. Full power all the time. Doesn't go into limp mode anymore. The exhaust note sounds great when fully hot but not in limp mode. I recommend every 350-370 owner get at least the 19 row street oil cooler. It won't void your warranty if the dealer installs it and your engine will love you for it. No need for the 24 row racing model if you're not racing.
