KR and running e85
Hi guys, I'm getting knock retard blips running a tad over 5psi on my 6.0l LQ9, the timing is at 15* when its at 5 psi around 3000 rpm. The turbo is a ebay gt45 and with no intercooler the intake temps are around 120F after a 0-70mph pull. Does this sound like false knock ? e85 should handle this no problem I would think? I would like to get 10 psi and keep the 15* of timing.
Thanks!
Thanks!

My buddy is running 5.5 psi in his 5.3 that has a small supercharger with IAT's in the 190+ range and 20* of timing and 92 octane it has no KR. Thats why this KR showing up on mine is kind of weird to me ?

I'm running the AC delco plug thats equal to the autolite 103 which I believe is stock heat range ? I was told they were good up to around 500whp and e85. I wonder if that is an issue ? I pulled the no. 7 plug yesterday and it just looked like a new plug, no coloring, there is around 600 miles on it. Sometimes the KR starts at 30% throttle with no boost then tappers off throughout the run after boost hits full on.
