Sorry for the confusion guys. Not 300 whp at altitude lol. I frequent between 4,500 and sea level because of my job, so we've been fine tuning it.
Here's the final 91 oct revision.
307 WHP at sea level with shit 91 oct e0-10% gas from New Mexico.
I'll just let these numbers speak for themselves lol. 307 on STRAIGHT 91 octane. That's 40 whp more than the x47 on 91. (269 is what's posted up on the x47 thread for 91 oct)
Got some more refined meth arriving on Friday to start that tune. Hopefully we don't hit fueling limits lol!
