uhh, map 7 is 16.5 pounds and tapers more than my map 5 with the e85 in the tank. Thats why. So if i can use map 5, hit 16.5 pounds, and taper less up top than map 7, why would i use map 7 over 5? Have you been living in a cave and not seen what map 5 + e85 does with the jb4?
the first page of the jb4 sticky says what boost levels map 7 runs.
