Just to add....
I ran my tank as low as I like to and filled up with Shell 91....
Maybe its just a coincidence but less knock....
Ill have it out on the highway tommorow and that will be a better tell since its hard to gauge fully on wet roads and in traffic.
I lied...shell knocks too....
Sorry to hear it man. That's gotta be frustrating.
"In Oldskool we trust"
Yup.....Going to run Shell for a couple more tanks. We are still on winter gas as well so that may make a difference.
The odd thing is the knock value never goes above 7.9....just goes to 7.9 and stays.
I was under the car the other day and doing a oil change and found my coolant pipe sitting on my intake manifold. I was so excited I had thought I found the source of the problem..lol.
This weekend the exhaust is going on...maybe its been plugged for a year.
Got the Aeroforce installed and I get 0 knock whether it be full throttle, part throttle, partial or full boost. This is on BP gas and then Speedway gas.
