someone mentioned that the LSN needle will not raise temps unless you idle it around. I would have to disagree with this, the LSN brings the motor temps up the fastest. You want to get it tuned to where it idles fine and has good performance with good smoke. Then you would mess with the HSN, the HSN is like a fine tuning needle. OD fuel is much better than the trinity fuel, has more oil than the trinity, thats probably why your motor ran color with the OD. If you were considering switching to 30% I strongly reccomend it, your motors will be much easier to tune, and will run better with the 30. just my $.02
