[QUOTE="paluka21, post: 15587189, member: 20747"] You shouldn't have to add 110 octane fuel to a street tune with a cold air intake, pulley, and throttle body. Something's not right with either the tune, your intercooler could be contaminated with oil, or something is amiss. I would suggest getting this sorted out before you move forward with adding high octane fuel to bandaid an underlying culprit. At idle 14:1 A/F ratio is just fine, but what you really need to pay attention to is the A/F ratio under the curve especially around peak torque. I prefer my A/F ratio to remain no higher than 11.5:1 which can provide some cushion for weather/temp changes and inconsistencies in octane. [/QUOTE]
