There is a local 'Unocal 76' that sells racing fuel (100+ octane) for $5.00 a gallon or so. I figure if I put $25.00 bucks in (5 gallons) with half a tank of 91, I will have a tank of 95+ octane or so. I will try it tomorrow and see if the sound goes away.
I have only had the car two months. How do I dial-down the boost? Is that a new chip?
