so how tight in 6th gear were u taching at the line? that's some low gearing even for a small shot. nitrous makes big torque, take advantage of it. the rpm window ur using for 2 step and launch seems safe at 600, however i caution u lowering that launch/activation rpm any more, lower activation than i recommend now, ur on such a small shot probabley ok, thing is cylinder pressure goes high instantley on spray, do not want to bog that bike on spray or spray too low in powerband. two seconds/50% ramped in leaves u a lot left, why 35 mph backhalf. u can spray that 15 shot full off the line, no ramp/100%, think u need a little gear as going to be going faster at 1/4. 1/8 times/mph will get u well into 8's. done a really good job on ur mods including nitrous setup, add a little gear, spray that full shot right off the line-gonna be surprised. bike gonna get real fast anywhere near the 30 shot if u ever go there, that probabley will require ramping with the mini controller u have. look foward to ur progress.
