[QUOTE="Voltwings, post: 15749847, member: 155561"] Oil does reduce the effective octane of fuel, even in small amounts. I have seen this on boosted cars i have tuned, but on a naturally aspirated car its a bit odd... What i have seen is that the dyno does not always load the engine / vehicle properly to hit the correct portions of the tables in the tune. For example, i tuned a car (different platform) to 28 psi on the street, but when we went to the dyno, the dyno was only producing enough load for the vehicle to target about 25 psi in the tune. What could be happening here, is the vehicle is not getting the required load from the dyno to hit the targets needed for the additional timing. Can you post those logs you've been taking? [/QUOTE]
