This weekend in Houston, It seemed that everyone was having issues with motors flaming out. The track temp ranged from 125-150 and the actual temp was around 98-100. When the track temp gets that high, what are the affects on the tune?

I tried to richen the bottom end, which helped but after the straight, halfway thru the sweeper the motor would flame out. A lot of guys had the same problem.... I was running the maxy 5 port " off road" with a 6 plug and 6.5 venture. Just looking for tips to help tune when the temp gets hot. The motor seemed to work well when the track temp was under 120... when it got to 150... it kept flaming out. thanks
