Great 60' ft's... Truthfully, if you want to get into the 12's without W/M, you need Torrie's tunes and perhaps a 100 octane Torrie tune if you can get 100 octane unleaded at the strip. My experience with 4+ was that it was .2 and 2 mph slower in the 1/8 mi than Torrie's 93 canned tune. This is from my runs at CF raceway in late Sept... when temps were much warmer. 81 deg... I turned a 8.59 1/8 at 81.6 mph. in the Flex. 4+ was around 8.86 @ 79 mph. 93 octane fuel + a bit ( small amount of E-85).
