They suggest 91 or better from the factory. I run 87 in mine with my nitrous tune. I just fill up with 91 before o spray. No KR. Idk if you are aware, but nnbs knock sensors are retarded sensative. You can tone them down a little and not hurt anything.

I have the tune back in running some e85,if you dont mind take a look tell me what you think,she pulls a lot of air thru the maf.
