The nistune run was running more timing at 4000 and was significantly leaner so naturally it made more power. The reason it was leaner was because Eric added throttlebodies which affected the tune AND he accidently ran the race gas tune on that run as he stated which was setup for more timing AND leaner mixture. I prefer to run a bit safer and conservative on pump gas tunes because i feel that for this customers application ( road racing) it would be more appropriate.
