So i did a WOT the other day in cold weather, and i got a 5* KR spike during my pull at 8.5 psi

Went to autozone got the NOS Racing formula octane booster with Nitro Methane. Did the same WOT to 105mph with a peak of 9.2 psi with 0* of KR

Just a FYI, believe it or not, just thought i would give people a heads up. I will be on e85 by spring and wont need this.
