Been chasing the 5.5 lbs very tough to hit. Does anyone know what the baseline actuator spring tension might be on a sea level mcx 200 kit for an Apex. As a baseline I set it so the adjustable tab would just slide over the flapper pin with almost zero tension with the flapper fully closed. I then was told to turn it in 1.5 turns. Is that how you establish your baseline boost setting ? When I tested in that position I was only getting 3.8-3.9 Lbs at 10,500. I then turned it in another 1.5 and only moved to 4.2-4.3 rpm up to 10600. At this rate I will have 6.5-7 turns in if my math's correct to get it to 5.5-5.7 lbs. Can I hurt anything turning it in that much ? When you spin the motor to 10800-11000 with that build more boost because I can always take some weight out to spin up the motor , thanks
