O/P, disregard everything this^^ poster said. DO NOT turn the LSN one full turn and run it.

JEZZZ....
You need to slowly turn in the LSN only 5 min on a clock each time until you get the proper throttle response, or launch your looking for. If your new to nitro or have any doubts about tuning, get yourself a temp gun.
